## Vega-Lite encoding dicts
|
You can use [Vega-Lite encoding dicts](https://vega.github.io/vega-lite/docs/encoding.html) for
|
the `x`, `y`, `color`, `size`, and `opacity` arguments to do all sorts of fun things. For example,
|
the chart below is computing the mean of the `y` values, grouped by month.

"""
|
Plost also supports [Altair-style
|
shorthands](https://altair-viz.github.io/user_guide/encoding.html#encoding-data-types), like
|
"column_name:T" for temporal.

You can add a minimap to many of the charts above my simply passing `pan_zoom='minimap'`.
