Summary
In this chapter, using an elections example, we covered spatial temporal data visualization and spatial relationship data integration. We also converted the data to TopoJSON, a format associated with D3, which greatly improves performance. We also created a spatial temporal animated web application through the D3 visualization library. In the next chapter, we will explore the interpolation to find the unknown values, the use of tiling, and the UTFGrid method to improve the performance with more complicated datasets.
