This interactive scatter plot visualizes the relationship between height and weight, with each point colored by gender (male, female, or no gender). Built as a reusable D3 chart component, it alternately animates the x-axis between the two variables every five seconds. The visualization uses `d3.scaleLinear`, `d3.extent`, `d3.axisLeft`, and `d3.axisBottom` APIs to render axes and circles over an SVG canvas. Data is loaded from a CSV of gender, height, and weight records.
