It probably means dots as in the click-on hotspots under the plot on these

To the meteociel graphic designer, those 3 dots looked like a string of
light emitting diodes, and diodes got in the text rather than LEDs

Yes, I thought it was probably something like that. The dots look like LEDs so the writer calls them "diodes". In French, DEL is also used as well as LED (= diode électroluminescente).

Same logic as "radio buttons": so-called because they look and act like radio buttons https://en.wikipedia.org/wiki/Radio_button
