Learned D3 at Businessweek, started using Observable to do my job at Kensho, took time off to write notebooks about Mayans and Galton, moved to San Francisco to work for Observable. Now work for it remotely from the Berkshires where my wife runs Avaloch.
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.)
