We have covered how we can complement charting techniques along with spatial data to provide a comprehensive insight into the data we have. While working with Infotemplate and dojo chart is handy, working with D3 provides greater flexibility and greater control over the graphical elements. Cedar, an open source data visualization library provided by Esri, is a great library for creating refreshingly new data visualizations very easily. Once we have mastered these techniques along with the statistical methods, and have learned to look at our data from different perspectives, we can claim ourselves as flag-bearers of map data science. There's one more component missing in the way we visualize our spatial data. That component is time. In the next chapter, we will see how to visualize spatio-temporal data along with the knowledge gained in advanced charting capabilities and the ArcGIS JavaScript API itself.
