[ ] Regression (behaviour that used to work and stopped working in a new release)

**Describe the Issue**
The first graph is showing a lot of grey, based on the burst box graph below I think it is incorrect and there should be more colour details.

**To Reproduce**
Replace the content below with the steps to reproduce the behaviour.
1. Go to http://212.111.41.68:8080/country/serbia
2. Click on 'international resources'
3. Scroll down to graph
4. See error

**Expected Behaviour**
For example I expected to see the colour for tourism on the graph

This is a medium priority, as it isn't a full blown data integrity issue is it less important than some of the other bugs in the backlog but it would be NTH for the ITEP update but not essential.
