Tooltip in Blazor Smith Chart component

Smith Chart will display details about the points through tooltip, when the mouse is moved over the point. By default, tooltip is disabled. To enable the tooltip, set the property Visible as true, in SmithchartSeriesTooltip. You can customize the tooltip’s visibility and appearance differently each series in the Smith Chart.
