As is typical, @Paul_Danyliuk always seems to pull a rabbit out of the hat. In this case, it’s missing an ear and maybe a foot, but it’s still an impressive approach - lots to learn in this one example.
But this underscores my plea for an investment in the integration of existing data visulization technologies, not the visualization features themselves. If Coda would endeavor to make it possible to embed Vega charts for example, every possible data visualization imaginable — including time lines — would suddenly lay at our fingertips.
Don’t make every feature we ask for - instead, help us help ourselves.
