Geospatial Clustering and drawing areas

Hello,

We have a dataset of crimes with their lat/long and danger score (recency, violence level, etc.). Sample rows below. I am now trying to draw bounding areas on the map that are colored by the score.
Is there a good example of this? I am sure its some clustering, some drawing… Help would be appreciated
