This scatter plot visualizes the relationship between the age and weight of individual cats, with each point colored by gender (blue for male, red for female). The code loads a CSV dataset via `d3.csv` and maps the data to positions using `d3.scaleLinear` for both axes. Interactive tooltips, implemented with D3 mouseover events, display breed, age, weight, and gender for each point. The SVG rendering includes labeled axes and a light blue background, all styled through standard CSS.
