This scatter plot visualizes the relationship between the Cost of Living Index and the Cost of Living Plus Rent Index for countries in 2024, using data from a Kaggle dataset. Each circle is positioned by the two indices and colored by rank from green to red via a linear scale, with a light gray inner rectangle framing the plot. The visualization is built with D3.js, using `scaleLinear` for axes and color, `extent` for data ranges, and custom `xAxis` and `yAxis` functions.
