This example demonstrates how to render D3 visualizations directly from a Node.js server, showing a line chart of normally distributed sample data. The server uses Node’s HTTP module and the D3.js library to generate SVG markup programmatically, then sends it to the browser as an `image/svg+xml` response. It constructs linear scales (`d3.scale.linear`), axes (`d3.svg.axis`), and a basis-interpolated line (`d3.svg.line`) entirely on the server side. The visualization is styled with simple SVG attributes, and the data is randomly generated via `d3.random.normal`, highlighting a server-side rendering approach where all D3 computations and SVG generation occur in Node before transmission.

D3

This example showcases a D3 visualization rendered as an SVG within an HTML page, loading the d3.v5 library from a CDN. The code sets up an SVG canvas of 960 by 500 pixels and includes a linked stylesheet, suggesting styled output. The visualization depends on an external JavaScript module (`/js/main.js`) that likely leverages D3’s core APIs to generate the graphics, though the specific chart type or data source is not visible in the provided files.

D3 in Action Chapter 11 - Example 6

This example demonstrates a hybrid rendering technique for large-scale network visualizations, using 3,000 nodes connected by roughly 1,000 random links. It first draws the nodes as red SVG circles, which retain mouse interactivity, while simultaneously rendering the edges on an overlay HTML5 Canvas for performance. A force-directed layout, driven by `d3.layout.force()`, updates node positions on each tick, clearing the canvas and redrawing the link strokes before repositioning the SVG circles. The approach balances interactivity with animation speed, leveraging both the Canvas `getContext("2d")` API and D3’s selection logic.

This example visualizes a force-directed graph using D3’s `d3.forceSimulation` to position nodes, with links drawn as SVG lines. The rendering approach uses Canvas `getImageData` to sample pixel data for a custom background effect, while Three.js handles 3D-like sphere rendering for node highlights. The code reads node and edge data from an embedded JavaScript object, and the simulation runs continuously with a `tick` handler updating node positions. A dropdown menu lets users filter the graph by cluster, though the filtering logic only updates node visibility without altering the underlying simulation forces.

d3 Chart Nodes Demo [yFiles for HTML]

This example combines d3.js bar charts with yFiles for HTML node styles to visualize dynamic data on an interactive graph. Each node displays a sparkline-style bar chart that updates every 500 milliseconds with new random data, simulating live server updates. The D3ChartNodeStyle class uses d3.scaleBand, d3.scaleLinear, and d3.interpolateHcl to render the bars, while yFiles manages the graph layout, edges, and user interactions like zooming and panning. The sample graph contains city nodes connected by edges, with labels positioned above each node.

Learning D3

This example demonstrates a minimal SVG visualization composed of three horizontal lines, each drawn as a black path across a 960-by-500 viewport. The code uses static path elements with explicit coordinates, showing how basic shapes can be rendered without additional data or interaction. It incorporates an inline SVG in HTML with CSS and JavaScript, serving as a starting point for learning D3. The visualization relies solely on predefined path data, not on D3’s data-binding or scale APIs.

My local D3

This example demonstrates the fundamentals of D3 version 3 for creating interactive SVG visualizations, starting with simple data binding and circle placement before progressing to a two-series line chart. The main visualization loads tabular data from a TSV file using `d3.tsv`, then applies linear scales (`d3.scaleLinear`) to map the x and y1/y2 columns to SVG coordinates. It renders two distinct line series using `d3.line` with step and natural curve interpolation, styled with purple and blue circles, and includes axis generation via `d3.axisTop`, `d3.axisRight`, and `d3.axisLeft`. The code also shows earlier iterations using `d3.select` and `d3.selectAll` for DOM manipulation.

Let's make a line chart with D3.js!

This example demonstrates how to build a line chart using D3.js v5, rendering the visualization as an SVG element within an HTML page. The code initializes an SVG canvas and prepares to map data to x and y coordinates, though the specific data array and line generator are not visible in the provided snippet. The example relies on the core D3 library for DOM manipulation and SVG creation, with the chart’s appearance styled through an external stylesheet. The rendering approach uses standard SVG paths, making it suitable for static or animated line-based data representations.

The visualization generates a random sequence of twenty charts, cycling through line charts, pie charts, and bar charts. Each line chart displays four smoothed monotone curves with colored dots, while the pie chart and bar chart render categorical and time-based data. Built with D3 v4, the code uses `d3.line`, `d3.arc`, and `d3.axisBottom`/`d3.axisLeft` to produce SVG output. Data is procedurally generated using `d3.randomUniform` and `d3.range`, with each chart styled via inline attributes and CSS classes.
