In your browser can you open the lower SVGSVGElement arrow?

oh oops, now you can. it wasn't working before for an unrelated (though also annoying!) reason: since the chart updated at like 60fps, the inspector kept re-rendering, and it loses its expanded state whenever it re-renders, which is filed as an issue https://github.com/observablehq/inspector/issues/12

Hmm...so, is the HTML/SVG created embedded in this somewhere? I opened a bunch of arrows and don't see anything that looks like what I would expect, which would be the HTML/SVG that the code creates...in this case, it would be the same as the code in the cell, but if the cell had D3 I would want the resulting HTML/SVG that the D3 created. <svg width="928" height="20"> <circle r="10" cx="464" cy="10"></circle> </svg>

Is the `chart.outerHTML` below what you want? You'd see `outerHTML` eventually in the prototype chain if you kept expanding arrows (it's in the Element prototype), but it shows in the Inspector as [forbidden] because you have to call it directly, like below. (That's a JavaScript thing that's more or less out of our control.)

Yes! But as a view on the cell that produces the code. I tried it on one of my notebooks but it didn't have linebreaks...one long line.

Oh, do you mean you want something like the "Elements" tab of Chrome's DevTools, that shows a live view of what's rendered?
