React funnel, cohort and gauge blocks

Conversion funnels, cohort retention grids, goal gauges and breakdown tables for React analytics dashboards.

Conversion funnel

Both drop-offs: from the previous step, and from the top.

A triangular heatmap as a real table, with numbers in every cell.

Arcs on a 0-110 scale, so over-capacity looks different from full.

Eight trends visible at once, with inverted colour where down is good.

One SVG circle each, with pathLength so percentages are literal.

Shares and totals derived from the rows, so the columns always add up.

Both rates that matter, with the worst drop-off called out.
