Define and implement data visualisation content type

[charlesons]

Design and create a structured content type for charts and their supporting text to enable us to store and re-use charts within the DD-CMS and broader IDS ecosystem.

Aims:

• For representing charts and their configuration within Plone-Volto.

• Ideally should be as generic/abstract as possible so as to be useful outside of the DD-CMS.

• Possible use for a chart library.

To do:

1. Look at existing standards / schemas for representing chart content.

2. Conversation between data engineering, product owner, devs and UX team on structure and flow of charts through the IDS ecosystem

3. Explore technical constraints of Plone-Volto and Plotly in defining this content type

Create a content type in plone that roughly follows

• [ ] Create content type through-the-web for "figure" as per #17.
• [ ] Look at image content type for how to store props locally in the block.
• [ ] Create content type for chart.

Could / should the figure block have a user configurable background colour? e.g. white smoke / rgb(245,245,245)

Review with @Alex next week

[charlesons]

Redefined the issue which previously had some overlap with issue #17 (implementation of the Figure content type).

Our understanding of the definition of content types and the relationship between them is evolving as we continue to build out more examples. In particular there's an opportunity to treat content as composable RDF fragments whose resultant structure can be queried and matched to a known higher order content type.
