Dark for me. The flow colors carry the whole chart and they read brighter against it. Did you check how the thin low-value flows hold up in light mode? That’s usually where sankeys fall apart.
Not 100% yet, I’m still exploring different styles and variations. I’ll definitely check how the thinner flows look in light mode. Good point, thanks for bringing it up!
Light mode takes the vote for data clarity. When hovering over a single source does the chart dim all other paths and highlight only that flow across to the outcomes.
Thanks! Yes, when hovering, the opacity of other elements decreases slightly, shifting the focus to the main information. Here, I have emphasized the visual aspect.
