Feature: 'Advanced view' to set nivo chart parameters not 'modeled' in the chart app

[johnaco]

I really like the idea of cypher -> chart (with nivo) . However, each chart has many parameters that could not be reasonably abstracted up to this app. It would be great if we had an 'advanced view' where the modeler could enter a valid chart parameter = one of the return elements of the cypher query and/or static values. That would provide much better control over the output.
