This example demonstrates an animated transition between stacked and grouped bar charts, with synchronized changes in position and size that preserve the identity of each bar segment. The visualization uses four series of fifty-eight pseudo-random values generated by a custom `bumps` function. The stacked layout defaults to view, and a radio button or an automatic timer switches to the grouped layout. The code leverages D3 v4 APIs including `d3.stack`, `d3.scaleBand`, `d3.scaleLinear`, `d3.scaleOrdinal`, and sequenced transitions via `transition()` calls, rendering as SVG.

AI-generated description

Switch between stacked and grouped layouts using sequenced transitions! Animations preserve object constancy and allow the user to follow the data across views. Animation design by Heer and Robertson. Inspired by Byron and Wattenberg.

Stacked-to-Grouped Bars

This example demonstrates an interactive transition between stacked and grouped bar charts, using sequenced animations to preserve object constancy as the data morphs between the two views. A radio button form toggles the mode, while D3 v4 APIs like `d3.scaleBand`, `d3.scaleLinear`, and `d3.stack` handle the layout and stacking. The transitions use `rect.transition()` with staggered delays and duration to smoothly animate each rectangle’s x-position, width, y-position, and height. The visualization renders with SVG, inspired by Heer and Robertson’s animated transition techniques.

transition grouped <-> stacked

This example demonstrates the animated transition between stacked and grouped bar charts. Ten random samples are displayed as five series, with the chart type toggling on a click. The visualization uses D3 v4’s `scaleBand` for categorical axes and `scaleLinear` for the y-axis. During transitions, `transition()` with duration and delay functions animates the bars’ positions and heights, reshaping the layout smoothly while maintaining the same underlying data.

D3.js: Animating Stacked-to-Grouped Bars

This example demonstrates an interactive bar chart that smoothly transitions between stacked and grouped layouts, with a single click on the chart toggling between the two modes. It uses D3.js v3 to render the chart as an SVG, animating the bars' positions and sizes via `transition` and custom attribute tweens. The data is generated in-browser with a `bumpLayer` function, and hovering a bar shows a tooltip listing the three series values using Underscore.js templates and jQuery for DOM manipulation. A legend with clickable series boxes lets viewers enable or disable individual series, updating the chart and the number of enabled series accordingly.

Grouped to stacked bar chart (random function)

The chart shows five series of ten random values that transition between grouped and stacked bar layouts. Users toggle the view using radio buttons, and the animation triggers automatically after two seconds. D3 v4’s `d3.stack` computes cumulative values for the stacked state, while `d3.scaleBand` and `d3.scaleLinear` position bars. The `transition` API animates bar positions, heights, and widths smoothly. Random, smoothly-varying data is generated by a custom `bumps` function, and the chart renders as SVG with an ordinal color scale.

This example demonstrates an animated stacked bar chart that transitions between stacked and grouped layouts. The chart displays five series of pseudorandom, smoothly varying data generated by the `bumps` function, with tooltips revealing precise values for each segment. Users can toggle the layout via radio buttons or an automatic timer that switches every two seconds. Built with D3 v6, the visualization uses `d3.stack`, `d3.scaleBand`, `d3.scaleLinear`, and `transition` with staggered delays to animate the SVG rectangles.

Stacked bar chart v4

This stacked bar chart shows ten samples across five series, with each series rendered as a color-coded segment. The visualization begins as a standard stacked bar layout, then animates the rectangles into a grouped arrangement, shifting the bars horizontally and adjusting their heights. Built with D3 v4, the code uses `d3.scaleBand`, `d3.scaleLinear`, and `d3.stack` to compute the stacked values and transitions. The SVG output is animated using the `d3-transition` library, with random data generated on the fly. The chart highlights how the same data can be represented in both stacked and grouped forms.

This interactive bar chart demonstrates the transition between grouped and stacked layouts using synthetic, smoothly-varying data. The visualization uses D3 v6’s scalable vector graphics (SVG) rendering with animation to morph bar positions and heights. Users toggle layout modes and toggle individual series on or off via custom radio-style buttons, which are built with D3 selections and manual layout positioning. The chart relies on `d3.stack` for stacked series data, `d3.scaleBand` for the x-axis, and CSS transitions for smooth updates.
