This interactive bubble chart displays the relationship between university research scores and international student rates, with each bubble colored by geographic region. The visualization makes it easy to compare regional clusters and identify institutions with high international diversity alongside strong research output. Loading data from a CSV file, the chart uses a D3 SVG rendering approach with linear scales for the x and y axes, a square-root scale for bubble sizing, and an ordinal color scale using the `d3.schemeSet2` palette. Interactive tooltips appear on mouseover, and the chart includes axis labels and a categorical legend.
