This line chart visualizes how country-specific data values change over time, with each country represented by a distinct colored line from the D3 categorical color scheme. It emphasizes comparison of trends across multiple series on a shared time axis, highlighting overall patterns and disparities in the dataset. The visualization is built using D3 v7, fetching data from a CSV file and rendering it as SVG. It uses `d3.csv` to load the data, `d3.scaleLinear` for both axes, and `d3.line` with `d3.axisBottom` and `d3.axisLeft` to draw the chart. The x-axis represents years, while the y-axis maps the numeric values, with rotated tick labels for clarity.
