I have developed a Chrome browser extension that sits in the sidebar, turning web page tables, lists, selected text or CSV pasted data into 2D and 3D charts. I developed this because it was such a hassle to copy all of the web page data and paste it into either Google Sheets or Excel just to be able to have it in a nice graphical form. It operates solely within the browser itself. Its free and it doesnt require any sign-ups.
