I’ve been looking for common standards for representing data in RDF, JSON etc ready for visualisation (eg for graphs, trees, charts etc), but without much luck.
I’m surprised how little there appears to be to find in this area. Let me know if you know of anything relevant.
My search for visualisation data standards has so far found few docs:
- defunct w3c group
- piecemeal proprietary docs
- never published vizJSON (IBM)
- Vega ‘visualisation grammar’ https://vega.github.io/vega/
Vega is promising: documented JSON formats for a wide range of visualisations, and with a JSON schema for validation and transformation. So fingers crossed Vega will be fairly easy to transform for use by other systems such as d3.
I just published an early version of the JSON ViewModel Specification which is being developed along with Visualisation Lab.
Feedback welcome, see: https://github.com/theWebalyst/visualisation-lab/wiki/JSON-ViewModel-Specification
