This example shows a 3D surface plot of a mathematical function, where the height at each point is determined by a cosine wave based on distance from the origin, scaled by a random factor. Users can drag the surface to rotate it in three dimensions, or click the "update" button to generate a new surface with a different random amplitude. The visualization uses d3._3d to project and draw the surface as SVG paths, with d3-scale-chromatic's interpolateSpectral for coloring and d3.drag for interaction. Each update transitions the new surface in over one second, dynamically recalculating the color scale domain based on the new height range.

An interactive 3D surface plot visualizes a mathematical function of two variables, rendered as animated SVG polygons that respond to drag gestures for rotation. The code uses the d3-3d library with d3.v4 to project points into 3D space, while `d3.drag()` handles mouse interaction to update rotation angles. Surface color varies by height using `d3.interpolateSpectral`. A button triggers `d3.randomUniform` to generate new function parameters, transitioning the surface over one second via D3 transitions.

3d surface

This example shows a 3D surface plot generated from mathematical formulas, with a menu to switch between three different datasets. The surface is rendered as an SVG path, with projected 3D coordinates transformed into 2D space. The code uses D3 v5 to bind data and create the SVG elements, while the surface geometry is derived from functions like sine and cosine applied to a grid of x and y values. Users can click list items to select a dataset, which updates the displayed surface.

This example shows an interactive 3D scatterplot and grid rendered with SVG, where users can drag to rotate the scene. Randomly distributed points float above a shaded grid surface, with projected axes and labels. The visualization uses the d3-3d library to compute 3D-to-2D projections, with d3.drag() handling rotation updates. D3 v4 transitions animate the initial point appearance, while React manages the component structure.

This example shows an interactive terrain visualization built with React and D3.js, displaying a 3D surface rendered on an HTML canvas. The code uses `d3.forceSimulation` to position nodes in a network layout, while `d3.geoPath` generates geographic shapes from projected data. The data appears to be a dataset of geographic coordinates, with the visualization applying a custom projection and color encoding to represent elevation or another spatial attribute. The scene is rendered through a canvas element, with the React framework managing state and updates between user interactions and the underlying D3 rendering pipeline.

A grid of colored 3D cubes displays varying heights, with each cube's height labeled numerically on its top face. Users can click an "update" button to refresh the data, which generates new random height values for each cube. The visualization supports interactive rotation by dragging the mouse, allowing the entire cube arrangement to be viewed from different angles. The code uses the d3-3d library to project cube vertices, computing visible faces and sorting them for proper depth rendering, while handling mouse drag events to update the rotation angles and re-render the SVG paths and text labels accordingly.

This example visualizes a grid of colorful cubes whose heights represent random negative values, rendered as an interactive 3D bar chart. Users can drag to rotate the entire scene, which triggers smooth transitions as the cube faces and numeric text labels update. The visualization uses the d3-3d plugin with d3.v4 to project cube vertices, while SVG paths and text elements render each face and height value. A button triggers regeneration of the data, and drag events control rotation angles through d3.drag.

Untitled

A 3D bar chart built with D3 v4 and the d3-3d plugin renders a grid of colored cubes whose heights represent negative random values. An update button triggers a 1-second transition that re-randomizes the cube heights, while text labels animate to show the changing magnitude. Users can drag the SVG to rotate the entire scene, adjusting the rotation angles via d3.drag and redrawing all cube faces and labels through the plugin’s projection and sorting methods.

Interactive 3D bar charts made of cuboids render in SVG, with height mapped to randomly generated negative values. Users rotate the entire scene by dragging, which triggers recalculation of all cube faces and the sorting of drawn elements for correct depth perception. The visualization uses D3 v4 with the d3-3d plugin for 3D projection and perspective, updating positions and labels with D3 transitions. An update button randomly regenerates the dataset, animating the new bar heights over one second.
