This visualization simulates a free-fall experiment using a micro:bit, displaying the measured fall time from a 4-meter drop in a line chart. It shows the relationship between elapsed time (in seconds) and fall duration, plotted across five time intervals. The code uses the micro:bit accelerometer’s `is_gesture("freefall")` to detect the start of the fall and calculates the time using `time.ticks_ms()`. It renders the chart with Chart.js on an HTML canvas, embedding the measured time as data points in the generated `CaidaLibreYupiii.html` file.
