This scatter plot visualizes the Iris dataset, showing the relationship between sepal length and sepal width. Each data point is represented as a colored circle, with colors distinguishing the three iris species: setosa in skyblue, versicolor in lightgreen, and virginica in orange. The visualization uses D3.js (v3) APIs including `d3.csv`, `d3.scaleLinear`, `d3.extent`, `d3.axisBottom`, and `d3.axisLeft` to load data from a GitHub-hosted CSV file, map values to pixel coordinates, and render axes with tick labels. The chart includes labeled axes for sepal length and width, with a red, centered title.
