In particular, and speaking as a backend engineer with zero web design skills, building things with charts/graphs is amazing nowadays! You can literally just operate at the level of "add another line representing the foo data", "add a scatterplot below it", "make them line up", "actually, make it a more reddish pink" etc. In the past I've had opinions about d3 and vega-lite and altair and matplotlib etc and learned how to use those ones at a superficial level at least. In my last personal UI with charts I didn't even ask it what framework it had chosen (chart.js is the answer)
