This is heavily modified implementation of the chart available at https://ubuntu.com/about/release-cycle It's not a complete rewrite, so there is some dead weight and non-idiomatic JS still present. There are weaknesses to this implementation: - The chart is invoked with raw HTML, which is bad form. - The chart data is stored in the JS file. A better way of passing data from the page itself, like an extension, would be superior. --- - [x] I've followed the [contribution guidelines](https://github.com/canonical/snapcraft/blob/main/CONTRIBUTING.md). - [x] I've signed the [CLA](http://www.ubuntu.com/legal/contributors/). - [x] I've successfully run `make lint && make test`. - [x] I've added or updated any relevant documentation. - [x] I've updated the relevant release notes.
