See Chart for examples of building a complete chart.

The chart signal component can be used to build complex Vega chart visualizations that respond to Vega Signal (opens new window) changes and update chart style or add chart markers.

Set value to a Flo.w reactive expression to update the corresponding Vega signal when the value changes.

Add a flowChartSignalChanged event listener to the chart component to react to signal changes originating in the Vega chart.
