About /embed

Notion's help describes /embed for websites and for uploading your own files. It does not say it renders an image URL, so use the image block. If you try /embed and see a Failed to Load error, that is Notion's note about sites that block embedding. Switch to the image block.

Limits that matter

The chart is fixed. It is the data inside the URL. To change a number, build a new URL and paste it again.
Paste the image URL. It starts with https://chartpng.dev/chart and points at the PNG, not at a web page.
Match the page. The chart keeps the background it was drawn with. On a dark page, add bkg with a dark color and the chart text turns light.
Free plan. The image carries the small chartpng.dev watermark. Anyone who can see the page can read the URL, so never put an API key in it.
Size. The config can be up to 16 KB. A typical image weighs about 20 KB.
