HW5 Stacked Bar Chart

This stacked bar chart visualizes the Times World University Rankings 2024, breaking down each university’s total score into five components: teaching, research, citations, industry income, and international outlook. Users can sort the 190+ institutions by any score category, in ascending or descending order. Built with D3 v7, the visualization uses `d3.stack()` to generate the layered bars and `d3.scaleBand` for the y-axis, with data loaded from a CSV. Interactive tooltips display individual score components and overall sums on mouseover.

HW4 Brushable Scatterplot Matrix

A brushable scatterplot matrix displays pairwise relationships among four Iris flower measurements (sepal length, sepal width, petal length, petal width) from the classic Iris dataset. Users drag a brush rectangle over any scatterplot cell to highlight corresponding points across all other cells, while unselected points dim. Diagonal cells show histograms of each measurement. The visualization uses D3 v7 with `d3.scaleLinear` axes, `d3.brush` for interactive selection, and SVG rendering; three Iris species are color-coded with distinct hex values.

Fork of Parallel Plot

This interactive parallel coordinates plot visualizes the Iris dataset, with each of the 150 flowers represented as a colored polyline tracing sepal and petal measurements across four vertical axes. Species are distinguished by color—setosa in green, versicolor in red, and virginica in blue—using `d3.line`, `d3.scaleLinear`, and `d3.scalePoint`. Below the SVG, draggable attribute labels let users reorder the dimensions via mouse events, triggering a redraw that repositions the axes and recomputes all paths.

Fork of Scatter Plot

This interactive scatter plot visualizes the Iris dataset, displaying measurements of sepal length, sepal width, petal length, and petal width. Users can dynamically select which numerical attribute appears on the X and Y axes via HTML dropdown menus, with points colored by iris species (setosa, versicolor, virginica). The visualization uses D3 v7 with SVG rendering, implementing `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` APIs. The chart redraws its axes and circles whenever a different attribute is chosen, with the y-axis dropdown preventing selection of the same attribute as the x-axis.
