NVD3

This example demonstrates an interactive multi-bar chart built with the NVD3 library, rendered through Vue.js and rCharts. The visualization uses SVG with animation to display categorical data across grouped bars, featuring hover effects that change bar opacity and display tooltips with detailed values. The chart includes standard NVD3 components such as axes, legend, and brush functionality, all styled through the included CSS. The base64-encoded stylesheet defines the visual appearance, including tooltip formatting, bar coloring, and SVG element styling. The implementation leverages NVD3's built-in chart types for grouped bar displays, with the rCharts wrapper providing the R-to-JavaScript bridge.

This animated SVG visualization, rendered with D3.js, explores how geometric forms can be generated through code. The page loads a script called `circle-lattice.js` that draws a grid of small, semitransparent red rectangles, each with a faint stroke trail that animates to show their movement or placement over time. The layout is minimal—a single heading "Scripts" above the canvas—and the emphasis is on the lattice of shapes as they are built and possibly repositioned, revealing structural patterns through the animation. The visualization uses D3's data-binding and SVG rendering to create a dynamic, generative composition.

D3 Example

Three bar charts are drawn as animated SVG rectangles that appear, update, and exit in sequence. The example demonstrates D3’s data-join lifecycle: `d3.scale.linear` maps data values to pixel positions, while `d3.transition` animates fill opacity over 2.75 seconds. Three timed `render` calls first draw two red bars, then five blue bars, then remove two while recoloring the remaining three green, with console logs showing the join state before and after each update.

Useful d3 v4 and js data snipets

This example demonstrates a collection of reusable D3 v4 and JavaScript snippets for data visualization, covering responsive SVG scaling, color scales, and shape generators. It includes a `responsivefy` function that adjusts SVG dimensions to its container, and showcases ordinal and sequential color scales, line and Voronoi generators with specific curve settings. The code also illustrates data transformation techniques using `forEach`, Underscore.js methods, and a queue for loading distant JSON data. Additionally, it provides a map implementation using `d3.geoMercator`, `d3.geoPath`, and a zoom interaction, with an SVG-based legend. The rendering is SVG-based.

This example shows a simple bar chart where each bar links to the D3.js website and changes color when a button is clicked. The chart is rendered with SVG, using d3.tsv to load data from a tab-separated file and d3.scale.linear to map values to bar widths. The color transition relies on CSS `transition` and the `classed` method to toggle a `.new-color` class on all rectangles. The README notes that this fill transition fails in Chrome when the target rect is inside an `<a>` tag with `xlink:href`.

Animated bar chart

This example demonstrates how to build an animated bar chart using D3 version 4. The visualization first draws a static cartoon-like figure composed of SVG shapes (rectangles, circles, and lines) to serve as a backdrop, then relies on a separate JavaScript file (index.js) to generate the chart’s dynamic elements. The code explicitly uses D3’s selection and arc APIs, including `d3.select` and `d3.arc()`, to construct the scene, with the bar chart itself styled via CSS classes such as `.bar` and `.highlight`.

D3 SVG Tutorial + D3 Animations Tutorial

This example combines SVG rendering with D3 animations by generating 50 random data points and plotting them as circles on a scatterplot with linear scales and axes. The visualization uses D3.js version 3.5.5 to create SVG elements, including circles, axes, and scales, while a button triggers animated transitions of the circles across the chart. The code includes both the SVG tutorial’s static chart construction and animation commands, though the author notes difficulty combining the two sections. Rendering occurs entirely through D3’s SVG API with interactive button controls.

D3 SVG Tutorial

This example shows a static bar chart of a 20-point dataset rendered as an SVG, with each bar’s height and color intensity tied to its value. The code uses D3.js version 3.5.5, applying the `d3.select` and `data().enter()` pattern to append rectangles and text labels. Bars are positioned with arithmetic on the dataset length and fixed width/height variables, while fill colors are generated as RGB values scaled by data. The chart demonstrates basic SVG shape binding and data-driven styling without axes or interaction.
