This interactive bar chart visualizes country-level data from a CSV file, allowing users to filter by continent and select among numerous socioeconomic metrics. The visualization updates dynamically, showing one bar per country, with bars sortable by population in ascending or descending order. Built with D3 v5, it uses `scaleBand`, `scaleLinear`, and `d3.select` for DOM manipulation, while rendering as SVG with animated transitions. Dropdown menus and buttons control the displayed subset, leveraging D3's data-binding capabilities.
