Chord HTTP API

POST /charts/chord
svgcanvashttp api

The Chordcomponent is available in the nivo HTTP rendering API. The API generates a SVG and return a path to this SVG which can then be easily embedded.

The api accepts almost the same properties as the regular component, in json, however it's not interactive and you cannot use code in properties (functions).

Please note that the demo API server is installed on heroku using a free plan, so it might be unavailable from times to times.

You can customize settings by using dedicated controls.
