How to add a chart to Notion
Notion has no native chart block, but it embeds images. Generate a chart PNG with a YakCharts URL and add it as an image — update the underlying data and re-embed to refresh.
Embed as an image
Create the chart in the visual editor or by URL, copy the image URL, and paste it into a Notion image block.
