Beyond Unicode, it should be possible to define a Web Component that generates SVG on-the-fly from a datasource.
Imagine:
<sparkline src="an image or csv"\>
One cool thing about SVG is it can inherit styles from your application, so you can produce e.g. dark-mode aware graphics rather easily, also one of the perks of this Unicode approach.
