Heatmaps from coordinates (python/matlab)

Hi, I need a bit of advice. I’m looking for a python or Matlab package, that would help me create heatmaps like the one below. Note: my data is not from eye-tracking, it’s an explicit free judgement task, so I have a bunch of X,Y coordinates and each selection RT. However, eye-tracking analysis seems to have the closest tools to analyse such patterns. Any recommended tools I could use?
