This scatter plot visualizes insurance data, showing the relationship between a patient's age and their insurance charges. Each point represents an individual, with colors encoding the patient's region of residence. The visualization is built using D3 v6, with a linear scale mapping age to the x-axis and charges to the y-axis. Data is loaded asynchronously from a remote CSV file via `d3.csv`, and circles are appended to an SVG container using data joins, with axes rendered by `axisBottom` and `axisLeft`.
