Update on Visualisation with Vega and Vega Lite
I’ve been doing more playing with Vega/Vega-Lite, even debugging them! I have eight different visualisations using on different data, again using Svelte
Next: use a single RDF source with output to all of the different visualisations.
Demo: https://svelte-vega-lite-eval.now.sh/
Code: branch test-visualisation-components
UPDATE:
UPDATE 1st April 2020
Quite a lot has happened to VisLab since my last post. You can use it to view the latest COVID-19 data for whichever countries you choose for example (and can zoom and pan the graph with the mouse).
Just now though I’ve been learning SPARQL so I can create interactive UIs which query sources like dbPedia.
So this is not strictly Solid, but related because SPARQL is a query language for Linked Data and you can also use VisLab to visualise the data on your Solid pod (very crudely for now).
dbPedia Example
Using dbPedia’s SPARQL endpoint I’ve made an example which creates a graph for Cnut the Great.
Try at: http://vlab.happybeing.com
- ‘SPARQL Query’ in first drop down
- ‘Cnut the Great and relatives’ in second drop down
- `Run Query’
- Scroll down for graph (click/drag/hove nodes)
- Uncheck ‘Show only the following fields’ to see the triples.
Feedback welcome!
