I love maps and was excited to learn recently about CartoDB, which allows you to build your own map in one click after importing data from a spreadsheet. In colored dots or heat maps, this visualization tool can easily show and compare death tolls, virus hotspots, or popular tourism sites…and a million other things. It empowers a writer to tell compelling stories and save a thousand words. I just began to use it. It seems an essential tool for anyone who needs to put data on a map.
