This dashboard visualizes the Pima Indians Diabetes dataset, showing the relationship between BMI and Glucose levels across patients, with age encoded by color and diabetic outcome by point shape. The D3.js v7 application faceted scatter plots group patients into age bins, displaying both individual data points and average glucose levels per outcome category. A third panel shows patient details upon selection, with linked highlighting between the scatter plot and bar charts. The code uses d3.scaleThreshold, d3.scaleOrdinal, d3.symbol, d3.brush, and d3.csvParse for data processing, binning, and interactive selection.
