2D Histogram & Heatmap

Hi everyone. I am new to Grafana and would like to get few clarifications on the below items.

  1. Do we have any plugins available that supports 2D histogram? If not, what is the recommended way or starting point to create the same?
  2. Does ‘Heatmap’ plugin works with non-time series data? (or) Do we have any other plugins that does the same?
