Changes in Version 3.0.0

This release introduces several changes that are backwards incompatible. On the plus side d3-geomap can now be imported via import or require from other npm modules. Many thanks to Dylan Praul for his substantial contributions.

  • 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.

Changes in Version 1.0.1

Changes in Version 1.0.0

d3.geomap was originally written in CoffeeScript. For version 1 I ported it to JavaScript or more specifically the EcmaScript specifications supported by babeljs.

In an effort to simplify the code and make it more readably and maintainable, I refactored the library internally. The public facing API stayed mostly the same, except for the changes listed below.

  • Turned svg accessor method into an attribute in d3.geomap.
  • Renamed zoomMax accessor to zoomFactor.
  • Renamed title accessor to unitTitle.
  • Removed data_by_id, selection, and private attributes from d3.geomap.choropleth.

New Features

  • Maps are now responsive by default if width is not set.
  • Added the duration and valueScale accessors to d3.geomap.choropleth.
  • Added colorScale and extend attributes to d3.geomap.choropleth.
  • legend accessor can now be called with an object having width and height attributes to set the legend dimensions.
