Bar chart (rotating + highlighting)

D3: A chart transition with controlled duration (labels, too!)

This example demonstrates a bar chart whose values, bar heights, colors, and labels all animate over five seconds after a user clicks the accompanying text. The chart initially displays a set of twenty numeric values as SVG rectangles, with corresponding white text labels positioned above each bar. The code uses D3 v4’s `scaleBand` for the x-axis, `scaleLinear` for the y-axis, and the `transition().duration()` method to smoothly interpolate the `y`, `height`, `fill`, and label text attributes when new data is applied. The dataset is a hardcoded array of numbers, rendered entirely via SVG elements.

D3: An SVG element tooltip

This example shows a bar chart built from a hardcoded array of numbers, with an SVG text tooltip that appears on mouseover to display each bar’s value. The tooltip is appended directly to the SVG and removed on mouseout. Clicking a bar sorts the rectangles in ascending or descending order using a staggered transition. The code uses D3 v4 with `scaleBand`, `scaleLinear`, and `transition` for sorting, while CSS `rect:hover` styling changes the fill to orange.

D3: Smoother highlight transitions

A bar chart displays a static series of twenty numerical values, rendered as SVG rectangles. On mouseover, the individual bar's fill immediately changes to orange, and on mouseout, it smoothly transitions back to its original blue shade over 250 milliseconds using D3 v4's `.transition()` method. The chart uses `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, with each bar labeled by its value via text elements that have pointer-events disabled.

D3: Sorting and re-sorting visual elements with delay

A bar chart of twenty numeric values renders with SVG rectangles and text labels. Clicking any bar triggers a re-sorting of the bars and labels in ascending or descending order, with each element transitioning horizontally to its new position. The code uses D3 v4’s `scaleBand` for x-positioning, `scaleLinear` for y-scaling, and `selection.sort` combined with `transition.delay` and `transition.duration` to create a staggered animation effect. Hovering a bar changes its fill to orange via CSS.

D3: Drawing a Bar Chart

This example demonstrates a basic bar chart built with D3 v7 in an SVG container, visualizing an array of 20 numeric values. The bars grow downward from the top of a 500×100 pixel canvas, with each bar’s height proportional to its data value multiplied by 4, and its fill color transitioning from dark to lighter blue based on the data. The chart also overlays each bar with white, 11px sans-serif text labels showing the exact data values, centered horizontally within each bar. The code uses `d3.select` to append SVG elements and the data-join pattern with `.enter()` to create rectangles and text nodes.

Vertical Bar Chart

This visualization presents a vertical bar chart initially displaying six pink bars with varying widths. The chart then animates, transitioning the bars to new width values over two seconds using D3’s transition system, with the `transition.attr` API handling the smooth dimension changes. The SVG rendering is implemented using `d3.select` and `append` to create the rectangles, while the data appears as static arrays within the code. The animation showcases how D3 can alter existing SVG elements dynamically, though the source data is not externally linked.

Making a Bar Chart

This example demonstrates a bar chart that is not yet fully implemented; instead, it shows a loading animation built with CSS keyframes. The display features four rotating line segments in yellow against a dark blue background, which rotate and fade to create a looping square-drawing effect. The code uses HTML, CSS animations, and D3.js from a CDN to set up an SVG container, but the actual bar chart data and rendering logic are absent from the visible files. The animation relies on CSS transforms with custom origin points to simulate a drawing motion.
