mathix420/notion-charts — reverse-engineered prompt

Build me a simple Notion charts app where someone can paste a Notion database link, pick the database view, choose which columns to use, and instantly get a nice chart they can embed back into Notion.

It should support public Notion pages, and also let someone self host it for private pages using their Notion token. The main flow should feel easy, not technical. Let users choose chart types like pie, line, bar, radar, doughnut, scatter, bubble, and polar area. They should be able to group by one column, then choose actions for other columns like show the value, count items, sum numbers, or average numbers.

Please include two outputs, one shareable interactive chart page and one image chart URL. Add a dark mode option so it looks good inside Notion dark theme. Make it deployable on Vercel, with clear setup notes for the private Notion token. Look up current docs online if you need to.
