Data Viz tips
Red/green is the most common CVD-failing combination in charts. Try your chart in deuteranopia mode — if red and green lines are indistinguishable, you have a problem.
Fix: use color + shape + pattern. Add markers (circles vs squares), line styles (solid vs dashed), or direct labels.
Modern chart libraries (D3, Chart.js, Recharts) have CVD-safe palettes — viridis, cividis, magma. Use those instead of red/green.
