New Visualisation Tools

Every month we're adding new tool reviews to our website on data visualisation for advocacy, Drawing by Numbers. Most recently we added reviews of:

Data Wrangler: is a free online tool that can be used to reformat, clean up and organise your dataset (produced by Stanford Visualisation Group)

OpenHeatMap: an online mapping tool that lets you create static or interactive animated maps and visualise changes over time (produced as a personal project by Pete Warden)
