This scatter plot visualizes the relationship between glucose and insulin levels in blood, with each point colored green or red to indicate whether a patient was diagnosed with diabetes. The data originates from the National Institute of Diabetes and Digestive and Kidney Diseases, focusing on female patients of Pima Indian heritage. The visualization uses `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for ticks, plus custom axis labels, all rendered through React and the d3 `select` API.
