Vega Themes

  

Themes for stylized Vega and Vega-Lite visualizations. For Vega version 3+ and Vega-Lite 2+.

A Vega _theme_ is a configuration object with default settings for a variety of visual properties such as colors, typefaces, line widths and spacing. This module exports a set of named themes, which can be passed as input to the Vega or Vega-Lite with Vega-Embed or directly as a configuration object to the Vega parser.

Try Vega-Themes in our Observable Demo.

Vega Themes comes with Vega-Embed:

``js
vegaEmbed(el, spec, {theme: 'quartz'});
`

If you want to use a different version, pass the theme as a configuration:

`js
vegaEmbed(el, spec, {config: vegaThemes.quartz});
`

Once instantiated, a visualization theme can not be changed. Instead, the input specification must be re-parsed with a new theme.
