This interactive visualization splits the Pima Indians Diabetes Dataset into two linked panels. The left panel presents a scatter plot of BMI against plasma glucose concentration, where each point is colored by patient age using a sequential inferno scale and shaped by diabetes outcome (circle for non-diabetic, cross for diabetic). Clicking a point highlights it in gold and dims others. The right panel simultaneously displays a bar chart comparing average glucose levels between diabetic and non-diabetic groups, computed with d3.mean. The visualization uses D3 v7 APIs including scaleLinear, scaleOrdinal, scaleSequential, symbol, and CSV parsing.
