I want to capture the data needed to create a visualization (data, series names, titles etc.) in a way that is not tied to my end charting library. The goal being that I could capture the charting data in a common way and let the UI take these definitions and transform them to target charting library at runtime (d3, high charts etc.)
Does anyone know of a robust / flexible data visualization schema that I could use?
"Data visualization" is a wide spectrum -- from tables to infographics, and everything in between.
But I did find one possible source: https://help.plot.ly/json-chart-schema/
The Plotly JSON visualization schema is a complete declarative format for creating, saving, and sharing interactive, scientific charts. The advantage of saving charts as JSON is portability - charts can be shared across any language or platform that understands the schema.
and an example:
{
"data": [
{
"x": [
"giraffes",
"orangutans",
"monkeys"
],
"y": [
20,
14,
23
],
"type": "bar"
}
]
}
The complete JSON schema is maintained as part of Plotly’s V2 REST API:
Fully formatted JSON chart schema for every chart type: https://api.plot.ly/v2/plot-schema?sha1=%27%27 Raw JSON (plain text) chart schema for every chart type: https://api.plot.ly/v2/plot-schema?format=json&sha1=%27%27
This page doesn't have license info, but plot.ly the company states this for plotly.js
