This example shows two bar charts: one displaying the top 10 most populous countries and another projecting emissions targets through 2050 with dashed goal lines. The SVG visualization uses D3 v5 scales including `d3.scaleBand` and `d3.scaleLinear`, with axes rendered via `d3.axisBottom` and `d3.axisLeft`. Data is loaded from CSV files using `d3.csv`, and populations are multiplied by 1000 to handle formatted values. The charts include interactive hover states and custom tick formatting that converts values to abbreviated notation.
