I am looking for the kendoui heatmap chart as found on GitHub or at the URL above.
I could just copy what they use on github, but I would prefer to get the kendo CDN all from one place.
Initial usage is just to render activity throughout the day as in github, extra is to track the onClick events as you usually want to trigger a re-query on what happened in that period of the day on that date, driving a details view elsewhere.
Al worse you could have dojo demo of how you would wire up chartjs-chart-matrix to a the Datasource(eg like https://demos.telerik.com/kendo-ui/map/geojson), with a view of how you would have created such a chart that would be good on a PWA app.
Thanks
