This scatter plot visualizes the relationship between subscriber counts and total views for the top 10 YouTube channels, with circle size encoding channel rank and color distinguishing country of origin. It uses D3 v7's `scaleLinear`, `scaleOrdinal`, `axisBottom`, and `axisLeft` APIs, rendering as SVG with interactive hover tooltips. The chart also includes a custom legend built with D3 selections. Data is loaded from a local CSV file using `d3.csv`.
