Third-party software and data

The map’s world geography comes from Natural Earth public-domain data, currently fetched through Plotly’s geography endpoint. Its manually maintained collaboration coordinates are part of this site’s original material.

The interactive collaboration map in assets/plots/colab_world.html bundles Plotly.js 3.3.1. Its original minified licence comments remain in that file. The following notices reproduce the licences for the bundled components. These terms apply to their respective third-party code, independently of the rights reserved for this site’s original material.
