> Two random thoughts... and these can be separate tickets/PRs if we want to do either of them: > > 1. This is the weird one: If you select to color the map by country, and deselect select "show bubbles," then you don't really need the Metric input (which is currently a required input). I thought for a second about making that input optional in that case... but in this configuration, the map is essentially useless, and doesn't tell you anything... so... whatever - fine as is. ¯\_(ツ)_/¯ > > 2a) You only actually need four colors to display a map. As a default, it might be nice to take advantage of that, if your mapping library happens to support the [four color theorem](https://en.wikipedia.org/wiki/Four_color_theorem) as a feature. > > 2b) If we do take advantage of the four color theorem, it may get ugly with color consistency... so... I don't quite know what to do there. > > 3. Also, with the color consistency thing... since a map might gobble up all the colors of a palette instantly, is there a good way to de-prioritize this chart (or others like it) it in the color assignment process? Thanks for these inputs! 1. Yeah. The only scenario I can think of for categorical color is that the user wants to have a world map in a dashboard, and the colors of different countries correspond to the series in different charts, and that's it, so let's just focus on the metric 😂. 2. -- This is an automated message from the Apache Git Service.
