AREA CHARTDescription
• Based on a line chart, showing layers• Shows how categories overlap• Displays comparisons through overlapping areas
Pro Tips• Useful to show volume comparisons over time• Use a stacked area to show distribution of related
measures over time• Good for trend displays
Avoid• Opaque colors• Too many metrics• Measurements that are too close in value (making it
difficult to distinguish a difference)
Use Case• Tracking multiple revenue streams over time, showing
total volume as well as distribution
Alternative / Related Visualizations• Line chart• Bar chart• Histogram• Combination: area-line / area-bar• Polar chart / radar chart
The use of distinguishable colors and semi-transparent fills allow the end-user to quickly see trends of independent values and how they compare to the other values within the same visualization.

BAR GRAPHDescription
• Shows values of specific categories• Compares absolute values of multiple items• Easy to interpret and compare
Pro Tips• Use stacked bar graph when comparing parts of a whole• Use to compare percentage to total of multiple items
Avoid• Graphing items with a broad numerical scale• Using too many contrasting colors• Showing zero (0) on the scale if it is not needed• Clustering a large number of items for comparison
Use Case• Comparing categories that are related to one another
(e.g. retail departments)
Alternative / Related Visualizations• Combination: bar-area / bar-line• HiLow stock / candlestick• Histogram• Gantt• Data cloud• Graph matrix• Microcharts• Cylinder• Thermometer• Pareto chart
Sorting a horizontal bar graph in a descending order allows the end-user to quickly ascertain the percentage share of one item compared to the rest.
A stacked bar graph is a great way to visualize the whole a of data element, as well as the components that make up its aggregation.

The box shape within the box plot represents the top three quartiles of a particular data element. The top part of the box is the first quartile, the bottom part is the third quartile and the line represents the median or second quartile. The whiskers, or high and low marks of the box plot, commonly represent the highest and lowest numbers of a data element.
In this example, the end-user can see that School District 200 has the most students that tested in the top three quartiles, while its median score is also the highest.

BUBBLE GRAPHDescription
• Lets users easily analyze three different metrics with bubbles of varying sizes
• Used to perform analyses involving key business ratios
Pro Tips• If data supports it, enable drill down to view more
granularity (e.g. drill down from states to counties, etc.)• Color by category and drill down sub-category• When appropriate and if the bubble graph visualization
supports it, add time as an added dimension
Avoid• Using if there is not enough screen real estate
Use Case• Showing birth, mortality, and total population by
continent then by country

BUBBLE GRIDDescription
• Helps identify correlations quickly• Color and size of the bubbles identifies where the item
lies on the spectrum between two metrics (e.g. color by profit, size by revenue)
Pro Tips• Ensure data has a wide variance, otherwise bubbles will be
too similar in size
Avoid• Coloring that is difficult to discern for those with color
blindness
Use Case• Measuring performance of product categories across
different regions

GRAPH MATRIXDescription
• Quickly analyze trends across multiple dimensions• Like microcharts, it offers a high-level view of a metric over
multiple categories
Pro Tips• Use like graph types across the matrix to identify true
comparisons• Use line or bubble graphs for optimal visualization
Avoid• Using unnecessary elements that may prevent
identification of the patterns
Use Case• Measuring healthcare member demographics and
utilization over time
Alternative / Related Visualizations• Bar chart• Line chart• Area chart• Microchart
The effective use of simplicity and clean layout allows the end-user to easily analyze trends across different dimensions. Patterns emerge that would otherwise need to be determined through a combination of visualizations.

HEAT MAPDescription
• Enables understanding of the impact of several factors simultaneously
• Metrics are represented by the size and color of each labeled rectangle
• Highly interactive: can pivot to remove attributes to create new comparisons, format colors, refresh to its original state, view deleted items, and use search functionality
Pro Tip• Use red, yellow, and green to indicate performance• Use monochromatic banding when performance isn’t
being measured
Avoid• Using unnecessary elements that may prevent
identification of the patterns• Using when metrics are unrelated• Using when metrics have too great or too small a variance
Use Case• Often used by the financial services Industry to review
portfolios
Alternative / Related Visualizations• Dual-axis combination graph when data has a high variance• Weighted list to view in a more linear fashion• Data cloud• Network
By using monochromatic shading, the user isn’t as inclined to see “good” or “bad” in the cells as much as they are to see volume of density of specific data elements.
Using a red-yellow-green gradient is a natural way to portray negative and positive indicators within a visualization.

LINE CHARTDescription
• Series of data points connected by curved or straight line segments• Shows trending over time• Good for quick interpretation and comparison
Pro Tips• Use different shapes of markers and colors to distinguish
one series from another• Use subtle horizontal grid lines for the y-axis to avoid
distracting from the data points• Use different line styles to show baselines, benchmarks,
goals, etc.• If showing a trend is more important than showing
detailed values, use minimal styling to create a “sparkline” type of visualization
Avoid• Using markers when comparing multiple items over many
data points• Comparing multiple items with similar values
Use Case• Comparing multiple measures over time
Alternative / Related Visualizations• Area chart• Bar chart• Polar chart / radar chart• Graph matrix• Combination: line-area / line-bar• Pareto chart• Microchart

MAPDescription
• View by geographies or with overlaid bubbles, sized according to metric data for effortless overview of geography comparison (e.g. state map, country map, store layout, etc.)
Pro Tips• Color code shapes to depict performance comparison• Consider differently-styled map pins to show different
categories (e.g. round, square, triangular pin, etc.)
Avoid• Using an entire map if only a specific subset needs to
be presented (e.g. use only the Northeast instead of the entire U.S. map)
Use Case• Healthcare system plotting different locations based on
service types (e.g. clinic uses square pin, hospital uses round pin, etc.)
• Color coding counties based on presidential election results
Alternative / Related Visualizations• None
Different map pin styles allow the user to differentiate one type of health provider from another.
Using existing color paradigms, like political
affiliation, is a natural and intuitive way for the end-user to gain deeper
understanding of your visualization.
Using gradients that follow the color wheel is an effective way to show density, especially on a map visualization.

MICROCHARTDescription
• Fits several intuitive chart formats into one area in combinations and formats of your choice (e.g. sparkline, bullet, and bar charts)
• View metric performance over time, specific values, comparison-to-goal data, and more — at a glance
• Small in design and dense in data
Pro Tips• Great to measure KPI trending• Best used for trending over time
Avoid• When needing to depict more than a summary-level
presentation
Use Case• Tracking KPIs across different geographies or product
categories
Alternative / Related Visualizations• Bar chart• Line chart• Area chart• Histogram• Graph matrix
Combining several small visualizations into one is not an easy thing to do. The visualization can become clogged and appear busy. This microchart shows that it is possible to combine several visualizations while still providing valuable insight and maintaining legibility.
The histogram part of the microchart allows the end-user to visualize the trend of a metric, as well as see it’s high and low in plain text.
This bullet chart works much like a box plot, with the exception that it doesn’t need to show quartiles. The dark gray indicates a low range of values, the middle gray indicates a medium range of values, and the light gray indicates a high range of values. The solid, vertical line represents a goal or benchmark, while the blue bar indicates the actual value of the metric. This example shows that the metric fell short of its goal and is within the medium range of acceptable values.
A line graph that is minimalistic in style is often called a “sparkline.” This sparkline enables the end-user to see the trend
of the metric without distracting them with additional clutter.

NETWORKDescription
• Great to depict relationships between related items, using nodes (circles) of varying sizes and lines of varying thickness that represent the relationships between the nodes
• Size of nodes and thickness of lines represent metric values
Pro Tip• Use colors to distinguish relationships and patterns
Avoid• Using if there are only small sets of data • If relationship connections are irrelevant
Use Cases• Retail stores demonstrating customer buying habits,
especially in terms of combinations (e.g. “customers also bought” visualizations)
• Tracking airline flight path metrics• Viewing relationships on LinkedIn or other social media
Alternative / Related Visualizations• Heat map• Graph matrix• Scatter plot
Showing product affinity and buying relationships effectively can be a daunting challenge. The network visualization is a great way to solve this problem. By both color coding and adding weight to the affinity lines, the end-user can quickly grasp relationships and their performance in relation to one another.

PARETO CHARTDescription
• Contains both a bar and a line graph• Values are represented by descending bars• Running % to total is represented by the line• Depicts percent to the total while displaying actual values
Pro Tips• Use to compare percentage to total of multiple items• Use subtle horizontal grid lines for the y-axis to avoid
distracting from the data points• Use different line styles to show baselines, benchmarks,
goals, etc.• If showing a trend is more important than showing
detailed values, use minimal styling to create a “sparkline” type of visualization
Avoid• Using too many contrasting colors• Graphing items with a broad numerical scale• Showing zero (0) on the scale if it is not needed• Clustering a large number of items for comparison• Using data markers when comparing multiple items over
many data points
Use Case• A retail store graphing the most commonly returned items based on defects
Alternative / Related Visualizations• Pie chart• Stacked bar chart
This valuable and easy to understand visualization is great for showing the age-old “80-20 rule.” By graphing absolute values on the bars and calculating a running percent to total on the line, the end-user can see where the 80-20 split occurs.

POLAR CHART/RADAR CHARTDescription
• Grid lines emanate from a center point, representing larger values for each additional outer line
• Data markers on the grid lines are connected by straight lines, resulting in shapes that visually depict data concentrations
Pro Tip• Shade with a semi-transparent color to show overlap
Avoid• Unless data is exceptionally suited for this representation• If data is consistently the same• Using if data contains numerous categories
Use Cases• Plotting common retail figures for various product
categories within a store• Showing multiple figures and their share in relation to one
another over an extended period of time
Alternative / Related Visualizations• Pie chart• Scatter plot• Bubble grid
This example quickly illustrates the relationship between two metrics across multiple categories. A larger, more spread-out shape would show that a metric is performing quite well. A smaller, condensed shape would illustrate that the metric could likely do better.
This type of visualization is a
great way to show the share of multiple
metrics over time. Florence Nightingale
provided the most famous example of
this visualization, diagramming the
causes of mortality in the military field
hospital where she worked.

THERMOMETERDescription
• Like gauge and cylinder, the thermometer visualization is effective for measuring the progress of a single metric toward a goal
• Arguably better than a gauge because the goal is at the top rather than at the side
Pro Tips• Use threshold color to indicate performance
Avoid• Using only red due to its negative connotation
Use Case• Tracking department sales goal in a retail environment
Alternative / Related Visualizations• Bar chart• Cylinder• Gauge
The classic thermometer shape makes it intuitive for the end-user to see how a metric can grow.

• This visualization is great for “what if” analyses (e.g. how sales could affect returns)
• Shows how different aspects of the business positively or negatively affect the bottom line
Pro Tips• Specify color for positive and negative values across metrics• Use for theorizing possible outcomes
Avoid• Using as a true predictive analytic tool
Use Case• A company adjusting their income and cost stream
projections in order to see how it would affect their bottom line
Alternative / Related Visualizations• Funnel
The use of different colors supports the ebb and flow of the descending and ascending bars. Typically, one might use green to indicate growth and red to indicate loss.
