List of inspiration sources for new map types

[jgaffuri]

• map with fill pattern. Test new fill patterns.

• map with stroke styles - patterns
• map with hand written stuff: Test https://roughjs.com/
• map with fill pattern (hashes?) indicating composition
• map with bar rectangle (only height varies) to show variations in quantities.
• map with time series for countries/regions: https://observablehq.com/@pjsier/chicago-covid-zip-sparklines

Add possibility to show shadowed effect for the countries AND buffered lines as on this image:

Show temporal data using:

As an alternative to pie charts, use other types of shapes do show decomposition (radial pie charts, squares (flag like), etc.). See some examples here, in some images at the bottom:

Make compositions possible?

• compositions chroploth + prop circle
• composition choropleth map showing variation (diverging colors) + rectangle/bar showing quantities +/-
