Visualization of data is a topic I have a more than passing interest in. It’s a fundamental part of my daily routine as I help people understand what they have and show them new methods and tools with which they can discern patterns that may be hidden.
Sometimes I find things that are interesting or just well done. Such as this earthquake data from the USGS. Looking at the image below you can see data points (location) with value (seismic strength) and recency (date/time) clearly and concisely.
