Our census application from previous chapters could use some visual appeal when it comes to presenting data. We'll make our first attempt at adding charts and graphs using the
dojox/charting library. We'll apply the graphs to the map popup whenever the user clicks on a census block group, county, or state. The census blocks don't have enough information for us to graph.
Since our graphs are currently limited to our census application, we need to update the modules in our custom
y2k/Census module definition:
dojo/onto handle the map popup events.
