Creating images for visualization

In Chapter 1, Learning Geospatial Analysis with Python, we visualized our SimpleGIS program using the Tkinter module included with Python. In Chapter 4, Geospatial Python Toolbox, we examined a few other methods for creating images. Now we'll examine these tools in more depth by creating two specific types of thematic maps. The first is a dot density map and the second is a choropleth map.
