A Sankey diagram visualizes the Car Evaluation dataset, showing how combinations of car attributes (buying price, maintenance, doors, persons, luggage boot, safety) flow to final acceptability ratings. The diagram uses color-coded nodes grouped by attribute type, with link thickness representing the count of cars with each attribute combination. The code uses d3.sankey for layout, d3.drag for interactive node repositioning, and d3.csv for data loading. The visualization renders as SVG, calculating node positions and link paths through the sankey.layout(32) function.

Data Visualization Homework 8: Sankey Diagram

A Sankey diagram of car evaluation data visualizes the flow of car attributes—buying price, maintenance cost, doors, persons, luggage boot, and safety—toward an acceptability outcome. The diagram renders nodes and curved links as SVG elements using D3.js v5, with the custom `d3.sankey` layout computing node positions and link widths. Draggable nodes allow interactive repositioning, triggering a relayout that updates link paths via `d3.sankeyLinkHorizontal`. Data is loaded from a CSV text file using `d3.csvParse`.

Data Visualization Homework 8: Sankey Diagram

This visualization is a Sankey diagram that depicts the flow of car attributes—buying price, maintenance cost, number of doors, person capacity, luggage boot size, and safety—toward a final evaluation of acceptability. The diagram uses nodes for each attribute-value combination and weighted links to show the sequential relationships between them. The code builds the graph by parsing a CSV file and then uses a custom `d3.sankey()` layout algorithm to position nodes and links, rendering the final output as SVG. Interactive dropdown menus allow the user to select which columns to compare.

Fork of Data Visualization Homework 8: Sankey Diagram

This Sankey diagram visualizes car evaluation results from the car.data dataset, showing how attributes like buying price, maintenance cost, doors, persons, luggage boot, and safety flow into final acceptability ratings. The diagram uses d3.sankey() to compute node positions and link paths, with nodes colored by attribute category and rendered as SVG rectangles. Links are grouped by source-target pairs and their thickness represents the count of cars with that combination. Interactive dragging of nodes is enabled through d3.drag(), allowing users to rearrange the visualization dynamically.

Fork of Data Visualization Homework 8: Sankey Diagram

This Sankey diagram visualizes car evaluation data, showing the flow of categorical attributes (buying price, maintenance cost, doors, persons, luggage boot, safety) into the final car acceptability rating. The diagram uses D3.js v5 to render nodes and links as an SVG, where node width represents the value of each category, and link thickness indicates the quantity of cars flowing between categories. The code defines a custom `flowDiagram` module with methods like `nodeWidth`, `nodePadding`, and `layout` to manage the diagram’s geometry, while a cubic Bézier curve function draws the links. The data is loaded from the `car.data` file, which contains comma-separated rows that are parsed into nodes and links.

Homework8

This example presents a Sankey diagram visualizing the relationships between categorical attributes of cars, using the classic car evaluation dataset. The diagram shows how each attribute value (such as "buying=vhigh" or "safety=low") connects to other attribute values, with link thickness representing the conditional probability of one attribute value given another. The visualization uses the `d3.sankey` plugin to compute and render the node-link layout, while `d3.csvParse` processes the raw CSV data. Each node is colored using a `d3.scaleOrdinal` with the `schemeCategory20` palette, and rendering is done as an SVG element. The code manually constructs nodes and links, calculating link values through data filtering, and displays the resulting flow diagram with interactive hover tooltips.

This visualization uses a Sankey diagram to show the flow of car attribute combinations from the UCI Car Evaluation dataset, sourced via a remote CSV file. It displays how categorical values for buying price, maintenance cost, doors, persons, luggage boot, and safety connect sequentially. The D3.js v4 code employs `d3.sankey()` for layout, `d3.csvParse` for data ingestion, and SVG rendering with `d3.drag()` for interactive node repositioning. Link stroke width represents frequency, while color encodes distinct source nodes.

Sankey diagram

This Sankey diagram visualizes the flow of car attributes from the UCI Auto MPG dataset, showing how combinations of buying price, maintenance cost, doors, persons, luggage boot, and safety lead to overall acceptability ratings. Users can reorder the attribute sequence using a dropdown menu, which rearranges the flow columns accordingly. The implementation uses the `d3-sankey` extension library on top of D3 v6, rendering nodes as rectangles and links as horizontal paths within an SVG canvas. Node and link colors are assigned via `d3.scaleOrdinal`, and nodes are draggable through D3's drag behavior.

109705001_hw8

This interactive sankey diagram visualizes the car evaluation dataset (cars.data), showing flows between six categorical features—buy, maint, door, person, lug, and safety—and the final class outcome. Users can drag column headers horizontally to reorder features and drag individual nodes vertically to explore the hierarchy. Hovering over links displays the count of records passing between each pair of categories. Built with D3 v5, it uses `d3.sankey` for layout and `d3.drag` for interactions, rendering SVG paths with stroke-opacity for flow emphasis.
