That's my js file. It get's the json data from the url("/uganda/report") above. When i navigate to the url i can see the json but for some reason the app has failed to display the graphs or map and is pushing out

Uncaught TypeError: Cannot read property 'forEach' of undefined

to the console. Am newbie to d3 so any assistance would be greatly appreciated.

This is some of the json i get for my "/uganda/report"
