> but hasn't ChatGPT had capability to create graphs and interact with data for a while?

It's pretty bad (for me). I have to use extremely prescriptive language to tell ChatGPT what to create. Even down to the colours in the chart, because otherwise it puts black font on black background (for example). Then I have to specifically tell it to put it in a canvas, and make it interactive, and make it executable in the canvas. Then if I'm lucky I have to hit a "preview" button in the top right and hope it works (it doesn't). I could write several paragraphs telling it to do something like what Claude just demo'd and it wouldn't come close. I'm trying Claude now for financial insights and it's effortless with beautiful UX.

For posterity, Gemini is pretty good with these interactive canvases. Not nearly as good, but FAR better than ChatGPT.
