This animated scatter plot visualizes the Iris dataset, mapping petal width against sepal length while coloring each dot by species (setosa, versicolor, and virginica). Built with D3 v3, it uses `d3.csv` to load data, `scaleLinear` for axes, and `setInterval` to cycle through different data columns every two seconds, updating the x-axis. The SVG rendering includes custom circle markers with varying dimensions and a rotating set of axis labels.
