This looks promising. I just created a visualization of 5M data points with Observable Plot and found it easy to make the plot aesthetically pleasing — there are a lot of examples, the built-in color scales are lovely, etc. But the browser really struggles to filter/summarize/render the data. On your Examples page, I would recommend making it more clear that these are live, buttery-smooth WebGL canvases. I thought I was looking at screenshots until I accidentally moused over the Health and Wealth of Nations plot. It would be more convincing to, say, put the scatter plot first, animate the points, and show the framerate. Give me a button to add 10^n points at a time and see how it performs.
