Bar HTTP API

POST /charts/bar

The Barcomponent 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.

Click the generate button in order to generate the chart.
You can customize settings by using dedicated controls.
