Changes in Version 3.0.0

• Provide a built version that other npm modules can consume with import or require.
• Rename d3.geomap.choropleth to d3.choropleth.
• Refer to the package as d3-geomap and to the JavaScript object as d3.geomap.
• Remove the colorbrewer object, which provided color scales. Instead d3-scale-chromatic, which is included in D3, can be used.
• The d3-geomap CSS class must be added to map elements for default styling.
• The TopoJSON files included in the distribution are now built from Natural Earth Vector version 4.1.0
• The downloadable zip bundle does not include the dependencies any more.
• The Rollup module bundler is now used for building the distribution.
• Upgrade to D3 version 5.

Changes in Version 2.0.0

• The draw function now only accepts a single argument, the map selection.
• Upgrade to D3 version 4.
