Graph as image #92

Although LVGL has its own chart widget, it could make more sense to use ESPHome's own graph component probably as an img because it already has a built-in data accumumator (eg you just give it a sensor ID and it starts collecting the points by itself over time) whilst chart needs a readily prepared set of datapoints to be displayed.

The nicest would be to just be able to use the id of a graph as the src of an img or animimg (animation would be useful to simply have a slideshow of graphs)

There LVGL chart can be updated at any time, so there is no reason it can't be made to work the same way.
