Online charts from public data

Applications for Belgium Contest

Data

• Public data exist in many formats

• Most of them are difficult to interpret

• Analyze is time consuming

Charts

• We believe that a clear visualization of data

helps its interpretation

• Charts easily highlight characteristics

Datacharts (DC)

• DC is a platform to generate charts online

• No technical knowledge is required

• Data from data.gov.be is preprocessed for

usage and made available on the platform
