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.

D3.js

This example visualizes a force-directed graph using D3.js v7, rendering nodes and edges within an HTML page styled with CSS. It employs `d3.forceSimulation` to compute layout physics, with the simulation updating node positions and drawing them as circles and links as lines onto an SVG or DOM element. The code loads data from an external source and dynamically appends SVG elements via D3’s data join, letting the structure respond to the imported dataset. Written as a minimal React-free setup, it demonstrates core D3 v7 APIs for interactive network visualization.

Fork of d3js

This example renders a horizontal bar chart of country populations using a React-free HTML page. It loads data from data.csv via `d3.csv`, then scales the values by 10 million. The visualization uses `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the y-axis, and `d3.axisLeft` and `d3.axisBottom` to draw the axes. Bars are appended as SVG `rect` elements within a grouped `<g>` transform, with height set by `yScale.bandwidth` and width proportional to population.

D3 Page Template

This example uses D3 v5 to render a simple bar chart. It creates an SVG canvas of 300 by 300 pixels, then defines a dataset of six numeric values. The code selects the SVG element, binds the data to it, and appends rectangles with widths proportional to the data values. Each rectangle’s height is fixed at 30 pixels minus a small gap, and its y-position is offset by index. The bars are uniformly colored steel blue. The rendering is purely SVG-based, using `d3.select`, `.append`, `.data`, and `.enter` to construct and position the bars.

[04] Animated bar chart - Using React Hooks with D3

This example shows an interactive animated bar chart where users can increment, decrement, filter, or append values to a dataset, with bars flipping vertically and transitioning smoothly to new heights. Built with React Hooks and D3 v5, it uses `scaleBand` for the categorical x-axis, `scaleLinear` for y and color interpolation, and `selection.transition()` to animate bar heights and fill colors based on a clamped color scale. The SVG rendering uses `transform: scale(1, -1)` to flip bars, with axes positioned via `axisBottom` and `axisRight`.

D3.js

This example uses D3.js v3 within a minimal React-free HTML page to demonstrate the core charting workflow. The code sets up an interactive visualization by selecting an empty body element and appending SVG or canvas elements via D3’s data-join methods. While the provided files contain only the basic scaffolding—a blank `index.html` and an empty `app.js`—the intended purpose is to show how D3 selections and scales build a chart from scratch. The documentation references D3’s force simulation and path generators as potential next steps.

D3 Chart

This example shows a static bar chart built with React and D3.js v4, displaying a simple dataset of nine numeric values as vertical bars. The bars are rendered as SVG rectangles, with heights proportional to the data values and positioned horizontally using a translate transform. The code selects the pre-existing `<svg>` element with the class `bar-chart`, sets its dimensions, and appends rectangles via D3's data join (`enter()` and `append()`). The chart uses `d3.select` and `d3.min` APIs to map values to pixel coordinates.

barChart and pieChart V3

This example shows how interactive bar charts and pie charts can be built with React and D3 v5, allowing users to switch between chart types and select different categorical columns from a dropdown menu. The visualization displays absolute frequencies of student grades and degree programs, with hover tooltips showing values or percentages, and animated transitions when switching data. It uses D3’s scaleBand, scaleLinear, scaleOrdinal, nest, pie, arc, and axis components, rendered as SVG with transitions and animation delays, plus custom tooltip handling via mouse events.

HTML Starter

This example demonstrates a stacked bar chart built with D3.js v5 and rendered as SVG within a React application. The chart visualizes five data points, each with three numeric keys (p, d, e), using `d3.stack()` to compute layer offsets and `d3.scaleBand()` and `d3.scaleLinear()` for positioning. Rectangles are appended via data joins inside groups, with each layer’s fill color assigned sequentially. The code includes placeholder divs for map and sankey visualizations, though only the bar chart is implemented.
