How to Use

Create the collection: ClearCollect(colLineDotData, {month: "January", Value: 186}, {month: "February", Value: 305}, {month: "March", Value: 237}, {month: "April", Value: 73}, {month: "May", Value: 209}, {month: "June", Value: 214})
On your screen's OnVisible, add: Set(varAnimLineDotChart, true); Set(varTooltipLineDotIdx, 0)
Paste the copied YAML into Power Apps Studio (Ctrl+V).
Click any dot on the line to show a tooltip; click again to dismiss. The selected dot enlarges slightly.
To replay the animation: Set(varAnimLineDotChart, false); Set(varAnimLineDotChart, true)
Replace colLineDotData with any data source that has {month, Value} columns.

Problem Solved

Renders a smooth SVG line chart with permanent dots at each data point inside a Power Apps Image control, with a grow-up animation.

Integration

Bind colLineDotData to any data source with {month, Value} columns. The chart redraws automatically when the collection changes.
