A very nice article, which gives an introduction to the not easy to understand topic GeoJSON. Thank you, Sumit.
Let me add that the format also allows the time information of a function (“time-stamped GeoJSON”) to be taken into account, which allows animated visualizations.
Now my question: I couldn’t find out which GeoJSON viewer, like geojson.io, allows quick looks into such time stamped files. How would this be possible, which tool provides an animation mode for time stamped files?
