Advanced charts

Advanced charts are a powerful way to display complex data sets. While less intuitive than basic charts, the visualizations should still tell a story the user can understand.

Choropleth map

A choropleth map uses differences in shading, coloring, or the placement of symbols within predefined areas to indicate the average values of a property or quantity in those areas.

Proportional symbol

Symbols driven by data are overlayed in geographical regions. A common symbol used is a bubble with the area of the circle proportional to its value in the dataset.

Connecting lines

Connection maps display points on a map connected by straight or curved lines.

Connection maps are most useful when showing connections and relationships geographically. They can also be used to display map routes through a single chain of links.

Connection maps are particularly powerful when revealing spatial patterns through the distribution of connections or by how concentrated connections are on a map.
