We use Choropleth maps to show differences in colors or shading of pre-defined regions like states or countries, which correspond to differences in quantitative values like total rainfall, average temperature, economic indicators etc
In our case we will use sales of a toy making company, as quantitative value, in different countries around the world. See example with thisjavascript based charting modules.
Rendering Choropleth Maps with Highcharts in Shiny- To see Highcharts/Shiny interaction, we will begin by creating basic Shiny dashboard layout: It contains a single select widget and single tab for displaying map.

Here we used library countrycode to convert long country names into one of many coding schemes. Adding new column iso3 in the summarized data with mutate function.
- Passing reactive object in renderHighchart function. Customizing tooltip and sub-title content with reactive widgets.
