The live reader is on this example’s HTML page. - Command line (Public agent tools 0.2.3, tested with Library 1.1.5; available from the versioned GitHub release and npm, https://westcoast-charts.com/docs/cli/index.md): `wcc chart export line-zoomable-timeseries.json --out line-zoomable-timeseries.svg --with-table` (save the options above as JSON first)
