Circle Data Visualization

A very common way to visualize large amounts of data is to use circles of varying size. We have improved our spreadsheet functionality for drawing circles, and the great part about using Scribble Maps to do the visualization is that you can also specify blend modes. Below is a US population circle visualization for the year 2000, the mode being used is median deviation; in this mode all cities who have exceptionally large populations or exceptionally small populations are represents by bigger circles.



Circle visualization is a great way to do some rough spatial analysis as well. To use this mode just load a spreadsheet in pro, and then select the associated options for drawing circles under the drawing tab.
