This example demonstrates a joyplot—a series of layered, filled-area charts—that updates its data every 100 milliseconds. It shows how the general update pattern can smoothly transition between datasets while preserving the visual identity of each layer. The code uses d3.area with a Catmull-Rom curve to generate the shapes, and d3.scaleBand and d3.scaleLinear for positioning. A d3.interval triggers redraws, and transitions animate changes to each path’s `d` attribute. The data is randomly generated per letter, producing alternating steelblue and tomato layers.

Use the general update pattern to make a joyplot. Joyplots inspired by Unknown Pleasures album cover.

Joyplot Update Pattern

This example demonstrates a joyplot update pattern, visualizing the distribution of three chemical response metrics (BmdA, BmdB, BmdC) across 50 chemicals using stacked kernel density estimates and rug plots. Each row in the SVG represents one metric, with a filled density curve drawn using D3’s area generator and a rug plot of individual data points marked as orange lines. The y-axis uses a band scale to separate the three distributions, while the x-axis maps the measured values. The code uses d3.v4 with SVG rendering, and includes an interactive tooltip library via d3-tip, though no explicit interaction is shown.

Joyplot

This joyplot shows the distribution of sports and leisure activity participation across the day, with each activity rendered as a filled, layered density curve. The x-axis maps time of day in 5-minute increments, while the y-axis encodes the proportion of participants. Each activity—such as Running—is represented by a separate row, with curves offset vertically and partially overlapping to create the classic “joyplot” ridgeline effect. The SVG rendering uses smooth paths to show the peaks and troughs of participation, making it easy to compare daily rhythms like morning and evening workouts, midday hobbies, and late-night outings. The chart is built with D3 v4 and the underlying data comes from the American Time Use Survey.

Update Pattern Trial

A bar chart displays monthly revenue and profit data from a JSON file, toggling between the two metrics every two seconds. Built with React and D3 v5, the visualization uses a band scale for months and linear scales for values, with axis transitions via `d3.transition()`. The update pattern joins data to SVG rectangles, animating height, position, and fill color as bars swap between tomato (revenue) and green (profit), while newly entered bars grow from the baseline.

Untitled

This example shows a continuously updating line chart that plots random data points in real time, with a smooth curve and a filled area beneath it. The chart scrolls horizontally as new points are added, while the x-axis shifts to keep the latest data in view. It uses D3 v4 scales and generators such as `d3.line` with `d3.curveCardinal` for the smooth path, `d3.area` for the fill, and `d3.axisBottom` for the axis. Animated transitions with `transition.attr` and `ease` shift both the path and area, with grid lines drawn as static SVG paths.

Bowl of Fruit - General Update Pattern Special Cases

A D3.js visualization animates a bar chart of twenty randomly generated data points, showcasing the general update pattern's special cases. The bars, colored with a gradient spectrum from RainbowVis.js, grow from the bottom to their respective heights over a one-second duration with staggered delays. The example uses the d3.select, d3.csv, d3.scaleLinear, d3.scaleTime, d3.extent, d3.axisLeft, and d3.axisBottom APIs within a barGradient function, rendering via SVG and animation. The data consists of random integer scores mapped to dates in June 2020.

Data Update Section

A grid of blue circles continuously updates in real time as their vertical positions and radii oscillate based on a sine wave function. The animation runs at 60 frames per second via a JavaScript `setInterval`, with each frame regenerating the dataset using `makeData` and passing it to `vizData`. D3 v5 handles the data join and SVG rendering, while the circles cycle through magenta and cyan color transitions using chained D3 transitions with ease functions. The example demonstrates dynamic data binding and stateful animations with ES6 module imports.

Path update

A line chart animates between two datasets, updating its path shape over time. The example uses d3.line to generate the path from an array of numbers, mapping each value to x and y coordinates based on its index and magnitude. D3’s selection and transition methods handle the smooth morphing of the path’s `d` attribute when new data arrives. The SVG rendering is driven by a simple render function called twice with different data arrays, demonstrating a basic update pattern with d3.v5.

10.transition-update pattern

The visualization demonstrates the D3 update pattern by animating a changing subset of the alphabet as text elements enter, update, and exit. The code defines separate transition states for each lifecycle phase—green for entering, dark gray for updating, and brown for exiting—using the `d3.transition` API with a 750-millisecond duration. Elements move horizontally to their new indexed positions, while exiting items fade out and shift downward before removal. The data shuffles and slices randomly every second via `d3.interval`, with the SVG output repositioning based on the current array.
