d3NoobV5 Reusable Examples - Sankey Diagram - v2 (with drag)

This Sankey diagram visualizes the flow of values between five nodes, with adjustable node positions through drag interactions. The chart uses the reusable chart pattern from Mike Bostock's "Towards Reusable Charts" and incorporates d3.sankey for layout computation, including node breadth and depth algorithms. Rendered in SVG, the code applies d3.drag for node movement and d3.scaleOrdinal with d3.schemeCategory10 for coloring. Links are drawn as curved paths with stroke widths proportional to flow values, and hover effects increase link opacity. The implementation follows Marcos Iglesias' ProD3 modular pattern with dispatchers for custom events.

SANKEY Experiment

A dynamic Sankey diagram visualizes the flow of values between five nodes using D3.js v5 and the Sankey plugin layout methods (`d3.sankey`, `sankey.layout`, and `sankey.link`). The SVG-based chart renders colored nodes and curved links with widths proportional to link values, supporting interactive node dragging via `d3.drag` to reposition elements and trigger `sankey.relayout()`. Data from a static JSON file defines node connections and quantitative weights, with hover tooltips showing source–target pairs and formatted widget counts. The example demonstrates custom link-path generation for a compact, explorable flow network.

SANKEY Experiment

This example uses a Sankey diagram to visualize the flow of values between five nodes, with links showing the quantity transferred from each source to its targets. The diagram is rendered as an SVG using d3.v7 and the d3-sankey plugin v0.12.3, with node rectangles colored using d3.scaleOrdinal and d3.schemeCategory10. Link thickness encodes the flow value, and hovering highlights the links. Data is loaded from a static JSON file (sankey.json) containing the node and link definitions.

SANKEY Experiment

A Sankey diagram shows the flow of values between five nodes (node0 through node4) across three stages, with links varying in thickness according to their assigned weights. The example uses d3.v6 with the d3-sankey plugin (v0.12.3) to compute the layout, generating SVG paths via `d3.sankeyLinkHorizontal()` for the links and rectangles for the nodes. A categorical color scale (`d3.scaleOrdinal` with `d3.schemeCategory10`) colors each node, and hover effects increase link opacity. Data comes from a static `sankey.json` file, demonstrating a basic multi-stage flow visualization.

SANKEY Experiment

This example demonstrates an interactive Sankey diagram with draggable nodes using d3.js v5. The visualization shows flow relationships between five nodes with seven weighted links, rendered as SVG paths and rectangles. The code loads data from a JSON file via d3.json, applies the d3.sankey plugin for layout computation, and uses d3.drag to enable node repositioning. A relayout function recalculates link paths dynamically when nodes are dragged. The diagram uses color from d3.scaleOrdinal and formats values as "Widgets" units.

SANKEY Experiment

A Sankey diagram visualizes the flow of quantities between five nodes, with node colors distinguishing categories and link thickness representing value. The diagram supports interactive dragging of nodes in both axes, recalculating link paths during movement. Built with D3 v4, it uses the d3.sankey plugin for layout and d3.drag for interaction. Data comes from a static JSON file, and the SVG rendering includes hover tooltips showing source, target, and formatted values in "Widgets" units.

SANKEY Experiment

This example shows a Sankey diagram with five nodes and seven links, where the width of each link is proportional to its value, and nodes can be dragged to rearrange the flow. The visualization is built using D3 v4 and the `d3.sankey()` plugin, which handles node layout and link computation, while the SVG rendering uses `d3.select()` to append paths and rectangles. The code uses `d3.drag()` for interactive node movement, and the data is loaded from a JSON file with `d3.json()`.

SANKEY Experiment

A Sankey diagram displays the flow of "Widgets" between five nodes, with links showing the directed transfer values. Built with D3.js version 3.5 and the sankey.js plugin, the SVG visualization renders nodes as draggable rectangles and links as curved paths whose thickness encodes flow magnitude. Data loads from an external JSON file, and the chart supports interactive node repositioning, which triggers recalculation of link paths through the sankey.relayout() method. Node and link hover tooltips reveal names and formatted values.
