This visualization displays the average population growth rate for each continent across five decades, from 1970 to 2010, using a pseudo line chart. Six distinct colored lines represent Asia (yellow), Africa (orange), North America (green), South America (purple), Europe (blue), and Oceania (red). Built with D3 v7, the code uses `scaleLinear` for both axes, `line()` generators to create each path, and `axisLeft` for the y-axis. The chart includes a gray inner rectangle background, axis labels for "Decades" and "Growth Rate(%)", and hardcoded data from the `index.js` file, with each line appended as an SVG path with a stroke width of 2.
