Summary
A link rather than a picture, which is exactly what you want when the channel can only carry text.
`GetChartImgLink` takes the entire chart definition in one `json` parameter and hands back a URL, so what the chart can express is set by Quick Chart's grammar at quickchart.io rather than by anything in this server. That makes the call trivial to make and moves the real work to knowing that grammar.
What it is
A single-call chart rendering surface: it takes a chart definition written in the Quick Chart API's parameter grammar and returns a link to the rendered chart image.
What you get
- A chart image link from a definition passed in `json`, written in the parameter grammar of the Quick Chart API at quickchart.io.
