Waterfall Chart
Native waterfall (bridge) charts. Declare an absolute `bar`, floating `delta` steps (+/-), and computed `total` bars; increases render green, decreases red, anchors blue, with dashed connectors and a value axis. The standard view for revenue bridges, variance analysis and budget walks.

The bridge a CFO puts on the results slide: FY24 EBITDA of £48,200k walks through price (+£6,900k), volume, mix and a subtotal after the revenue drivers, then raw materials, the energy saving, the wage settlement, the efficiency programme and FX, to FY25 EBITDA of £51,900k (+7.7%). Every bar is computed from the one before it, so the bridge always closes. Illustrative values.
Twelve months of annual recurring revenue from $24,600k to $30,300k (+23.2%): new logos add $5,200k, expansion $3,900k, and contraction and churn take $3,400k back. From the same bars, net revenue retention is 102.0% and gross revenue retention 86.2% — the two numbers a SaaS board asks for first. Illustrative values.
A manufacturer's scope 1 and 2 emissions from an 18,400 tCO₂e 2019 baseline to 13,060 tCO₂e in 2025 (-29.0%): four decarbonisation projects remove 9,270 t, while production growth and a new site add back 3,930 t — the honest bridge that separates what the projects achieved from what growth gave back. Market-based scope 2. Illustrative values.
