This bar chart ranks the ten most populous sectors of Chandigarh, with Mauli Jagran and Ram Darbar tied at the top. It uses a horizontal layout with population on the x-axis and sector names on the y-axis. The visualization is built with D3 v5, using `scaleLinear`, `scaleBand`, `axisBottom`, and `axisLeft` to render SVG elements. Population values are loaded from a CSV file and formatted in thousands, while axis ticks and labels are styled via an external stylesheet.
