This example displays the classic Iris dataset in a parallel coordinate plot, with each of the four floral measurements mapped to vertical axes and individual flowers drawn as colored polylines—red for setosa, green for versicolor, and blue for virginica. The visualization uses D3 v5 with SVG rendering, employing `d3.scalePoint` for horizontal axis placement and `d3.scaleLinear` for vertical scaling. Users can drag any axis horizontally via `d3.drag` to reorder dimensions and explore correlations between variables. Data comes from the bundled `iris.csv` file, and the code also renders axis labels and a legend.

Iris Parallel Corrdinate Plots

This example visualizes the classic Iris dataset using parallel coordinate plots, showing four flower measurements across vertical axes with polylines colored by species. Users can hover over lines to highlight all flowers of the same class while dimming others, or drag axis labels to reorder dimensions. The implementation uses d3.csv for data loading, d3.scaleLinear and d3.scalePoint for scales, d3.line for path generation, d3.axisLeft for axes, and d3.drag for interactive axis repositioning. Transitions animate the line redrawing during drag operations.

Iris Parallel Coordinate Plots

This visualization uses parallel coordinate plots to display the classic Iris flower dataset, with each of the 150 samples represented as a polyline across four axes: sepal length, sepal width, petal length, and petal width. The three Iris species are color-coded—red for setosa, green for versicolor, and blue for virginica—making species separation patterns visible. Built with D3 v3, the code uses `d3.svg.line`, `d3.svg.axis`, and an ordinal scale for axis positioning. Users can drag any axis title to reorder dimensions, which triggers a smooth 100-millisecond transition as the lines redraw. The data is loaded from a CSV file using `d3.csv`.

Iris Parallel Coordinate Plots

The Iris Parallel Coordinate Plots visualize the classic Iris dataset, with each flower sample drawn as a polyline across four measured attributes. Species are distinguished by color: orange for setosa, blue for versicolor, and green for virginica. The visualization uses D3.js v3 with SVG rendering, featuring interactive axis dragging to reorder dimensions. The code leverages D3's ordinal scale for categorical colors, linear scales for numerical axes, and the `d3.behavior.drag` API to enable axis repositioning. Background polylines appear in light gray for context, while foreground lines are colored by class.

Iris Parallel Coordinate

This visualization displays the classic Iris dataset as a parallel coordinate plot, with each flower’s four measurements (sepal length/width, petal length/width) drawn as a polyline across four vertical axes. Each line is color-coded by species using a D3 ordinal scale. The chart supports interactive dragging of any axis to reorder dimensions, with paths smoothly transitioning to the new layout via D3 transitions. All rendering is done with SVG elements, and the code leverages d3.scalePoint, d3.scaleLinear, d3.drag, and d3.axisLeft.

Iris Parallel Coordinate Plot

This visualization displays the classic Iris dataset as an interactive parallel coordinate plot, with each flower’s four measurements (sepal and petal length and width) connected as a colored polyline. Lines are colored by species using a scaleOrdinal mapping, and a side legend identifies the three classes. Using d3.csv to load data and d3.line to generate paths, users can drag any of the four axes horizontally to reorder dimensions, with d3.drag updating axis positions and sorting the column domain, followed by smooth transitions that animate the paths into their new arrangement.

Iris Parallel Coordinate Plot

This visualization uses a parallel coordinate plot to display the classic Iris dataset, with each flower’s sepal and petal measurements drawn as a polyline across four vertical axes. Lines are color-coded by species—setosa in green, versicolor in purple, and virginica in red—at 40% opacity to reveal clustering patterns. Built with D3 v5, the code uses `d3.scalePoint` for axis positioning, `d3.scaleLinear` for per-dimension value scaling, and SVG paths generated by a custom `path` function. Species colors are assigned through a conditional `class_color` function rather than a categorical scale.

Iris Parallel Coordinate Plot

This interactive parallel coordinate plot visualizes the classic Iris dataset, showing four floral measurements for three species. Each semi-transparent polyline represents one sample, colored by species (orange for setosa, teal for versicolor, purple for virginica), with draggable axes that reorder via `d3.drag` and animated transitions. A dropdown toggles the y-axis scale between a fixed union range (0–8) and per-axis extents computed with `d3.extent`. The SVG renders axes via `d3.axisLeft` and lines via `d3.line`, with species colors mapped through a custom function.

Iris Parallel Coordinate Plots

This interactive parallel coordinate plot visualizes the Iris flower dataset, displaying four measurements (sepal length, sepal width, petal length, petal width) as vertical axes with polylines colored by species. Users can drag any axis to reorder the dimensions, which immediately redraws the paths and scales. Built with D3 v4 (d3.scaleLinear, d3.scalePoint, d3.axisLeft, d3.drag), the SVG rendering uses data from iris.csv, with distinct colors for Iris-setosa, Iris-versicolor, and Iris-virginica.
