Is there a template available for tweaking heatmap panel plugin?

We have a template for tweaking the existing graph panel plugin
Link: https://github.com/CorpGlory/grafana-graph-panel

Do we have a similar kind of template for heatmap panel development?

I tried using the source code available in grafana master but it does not have dependencies or package.json

Please share me if any template is available for the heatmap panel plugin development
