World App Worldcoin Graph Interaction

This interaction demonstrates a highly responsive line graph scrubbing gesture. When the user drags their finger across the chart, a vertical line and tracking dot appear instantly, following the curve of the graph. A floating tooltip emerges above the dot, displaying the specific price and timestamp for that data point. Simultaneously, the main price label on the left updates in real-time to reflect the scrubbed value. The tooltip smoothly translates horizontally, scaling and fading out gracefully once the user releases their touch.
