xkcd’s take on mapping, via Duarte Romero
In a previous post I explained some of the considerations in deciding to use a map in data visualisation, and went into detail about mapping points and heatmaps. In this second part, taken from the MA in Online Journalism at Birmingham City University, I’m going to look at other types of maps: shape-based maps and image maps.
A more ambitious alternative to mapping points is to map shapes: in other words, instead of each data point being placed on a specific point on a map, instead different areas on that map are drawn and coloured/labelled according to the relevant data.
