Area Tooltip Card

A white KPI tile with a fourteen-day filled area chart, a quiet baseline, a few date ticks, and a tooltip. When the card comes into view, the area fades in and the top line draws from left to right. Hover a day, or focus the chart and use the arrow keys, and a small tooltip shows that day's date and value. Swap the label, value, delta, points, and dates, then drop it into a dashboard row or an analytics feature grid.
