This interactive scatter plot visualizes United Nations Development Programme data, mapping countries by their Human Development Index and maternal mortality ratio. A small multiple display changes the x-axis variable between revenue, release year, and popularity via control buttons, with hover tooltips revealing detailed country information. The visualization uses D3 version 5, loading CSV data from a GitHub gist and employing `d3.csv`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and custom tooltip styling.
