This example displays a column chart of monthly air traffic between India and other countries, using passenger counts from a CSV file. The code loads the data with `d3.csv`, then builds a Google Visualization `DataTable` through `google.visualization.arrayToDataTable`, styling each bar with a custom fill and stroke color. The chart is rendered as a `google.visualization.ColumnChart` with a title and legend, while the underlying data source is a raw GitHub-hosted CSV.
