Description:
http://andculture.com/lab/designing-with-data A presentation explaining the importance of visualizations. I begin by reviewing some general theories about translating data into visuals, and then dive deeper into some specifics for using qualitative and quantitative information to tell your story. Finally I close by discussing some more technical details that everyone making visualizations should be aware of. It was geared towards an internal audience that has varying levels of technical understanding regarding the artistic, psychological, and narrative principles that inform well made visualizations and infographics.

People are visual learners.

“… 80% of the information we take in is provided by

our eyesight.”

INTroDuCTIoN

Visualizations help everyone.

1. Making them provides further insight into the information

2. Visualizations invite comments and inspired discussion

3. Enable presentations that aren’t reliant on scripts or memorization

Sure it seemed like a lot before, but you may have also thought there was a lot of these other locations. This helps highlight the differences in perception of “a lot.”

I assume the decision to illustrate this as a sketch is to make something potentially scary and dangerous seem more approachable.

Bar Chart.

“The biggest benefit of bar charts is that different tems of data can easily be compared visually.”

stacked Bar Chart.

“Stacked bar charts describe totals while allowing a degree of internal breakdown of the data.”

histogram.

“…in a histogram it is important to retain and display the empty space. It contributes to the picture of the data as a whole.”

Whiskers.

“…whisker is a small vertical line representing plus or minus two per cent from the value, with some horizontal lines to make the ends easier to see and measure.”

Candlestick chart.

“The whiskers, or wicks, that extend up and down do not measure margin of error, but the maximum and minimum…” where the bar represents the starting and finishing points.

Page 27: Designing with data: Creating Visualizations to Tell Your Story

GrAPh TyPEs | PIE CHART

“…a pie chart can only represent relative amounts.”

“The most effective pie charts comprise only two items, such as the percentage of male or female customers.”

“The total value of the information must add up to one hundred per cent…”

Brian Suda, A Practical Guide to Designing with Data, pg 132

“Line graphs work best when the data is continuous.”

“one of most common variables used in line graphs is time…”

scatter plot.

“Scatter plots are a useful tool to reveal relationships between any amount of independent values. …The data points are placed in a grid in an attempt to build a larger picture.”

“We add together all of our test results and then divide it by the sum of the total number of marks there are.”

“The Median is the ‘middle value’ in your list.”

“the amount of ink representing the data divided by the total ink on the graph”

Don’t be confused; the data–ink ratio is not advocating the use of as little ink as possible, but only as much ink as needed to convey the data

for Print Media.

It is preferable that documents are at least 300dpi.

for Digital Media.

It is preferable that documents are at least 72dpi.

Page 41: Designing with data: Creating Visualizations to Tell Your Story

DETAIls | CoLoR

Color can do a lot to help clarify information on a chart. However, mis-use and it will only add to the confusion.

Be mindful of how you use color. It can easily be overdone.

Try starting with black and white, then adding color later.

Page 42: Designing with data: Creating Visualizations to Tell Your Story

DETAIls | LEGENDS

As nice as it can be to have a very “clean” visualization or chart, if it doesn’t convey the necessary information it is useless.

Make sure, if you do use distinctions such as color, shape, size, etc. to differentiate data, make sure it is labeled and clear.
