This example shows the distribution of response durations across seven time bins, from under one minute to over six minutes, with the largest share falling in the three-to-four-minute range. It renders a three-dimensional pie chart using the Google Charts loader and the `google.visualization.PieChart` API, setting `is3D` to true for the visual effect. The data is embedded directly in the page as an array passed to `google.visualization.arrayToDataTable`, and the chart is drawn into a fixed-width div. The title labels the chart “duration_ms,” though the axis categories use human-readable minute ranges.
