vega-projection-extended

Extended projections for cartographic mapping.

This package extends Vega's set of cartographic projections with those provided by the d3-geo-projection library. See the index.js file for the complete list of imported projections.

Usage Instructions

To use this module in a web application, include the appropriate compiled JavaScript file as a script import on a web page. The library produces two output files:

1. vega-projections.min.js contains all extended projections plus required methods from the d3-array and d3-geo libraries.
2. vega-projections-core.min.js contains the extended projections only and expects a stand-alone version of D3 to have already been imported.

If you are using the standard vega.min.js builds, include the following after Vega has been imported:

  <script src="vega-projections.min.js"></script>

If you are using a standalone version of D3 (for example, alongside vega-core.min.js), you can use the smaller file instead:

  <script src="vega-projections-core.min.js"></script>
