How these alternatives were chosen
Tools D3.js names as alternatives that this directory also publishes, followed by others in Library. The order is not a ranking, and "—" means we have not checked that field — not that the answer is no.
D3.js also lists Observable Plot, Plotly, Vega, Apache ECharts, Recharts as alternatives. Those are not in this directory yet, so there is nothing to compare — and nothing to link to.
