There is an interactive map on website like this: https://www.bostonglobe.com/2021/12/15/nation/these-are-all-massachusetts-towns-that-have-indoor-mask-mandates/#bgmp-comments
Where when the mouse hovers on it, it will highlight that area and show info for that certain area. How to get the data behind these and exact all the data to excel etc.? Is it written in Javascript?
