[Feat]: ability to "press play" from on a chart

[andrewm4894]

Problem

i would like to be able to have a chart in play mode and updating while i am hovering over the chart - its a bit annoying to have to press the play button and then make sure i dont hover over the chart by accident and end up pausing it again

Description

i want a play button on the chart itself so that i can unpause easily from on a chart

Importance

really want

Value proposition

1. would make charts easier to work with

Proposed implementation

a play button somewhere on the chart that would un-pause things.
