It uses `ui.Chart.image.seriesByRegion` with parameters: `imageCollection`, `regions`, `reducer`, `band`, `scale`, `xProperty`, and `seriesProperty`. The x-axis represents images labeled by `xProperty`, the y-axis shows the reducer's output, and series are labeled by `seriesProperty`. It takes data from an `imageCollection`, reduces it based on regions, and displays the results in a chart, frequently displaying a time series. An example provided uses MODIS vegetation indices.\n"]]
