This interactive D3 v4 bar chart displays two datasets of numbers as vertical steel-blue bars with value labels and a y-axis. Clicking the Update button toggles between a 10-element ascending dataset and an 8-element descending one, demonstrating the enter, update, and exit pattern. The code uses d3.scaleLinear for the y-scale, d3.axisLeft for the axis, and transition().duration(500) to smoothly animate bar heights, positions, widths, and labels when the data changes. SVG rendering handles all visual elements.

D3 Practice - Animated Bar Chart

Eight vertical bars represent a fixed dataset of eight values at the start height of the chart. Upon loading, the bars animate upward via staggered delays and varied durations, with bars over the 300 threshold turning red while the others remain blue. The visualization uses D3 v4 with `d3.scaleBand` and `d3.scaleLinear` for positioning, and `transition().duration().delay()` for the animation, rendering as SVG rectangles within an axis-labeled coordinate system.

Bar Chart interactive

This interactive bar chart visualizes a dataset of 50 random values, with bars colored on a blue scale and labeled with their numeric values. Clicking the text prompt triggers an update that replaces the data with 25 new random values, resizing the bars accordingly. Built with D3 v6, the example uses the scaleBand and scaleLinear APIs to map data to SVG rectangles, while the d3.select method binds the click event to the paragraph element.

D3: Adding values and elements to a chart

A bar chart displays a fixed dataset of 20 values as blue rectangles with white value labels, using D3 v4 scales (`scaleBand` and `scaleLinear`) and SVG rendering. Clicking the text above the chart triggers a transition: a random number between 0 and 25 is appended to the data array, the scales’ domains are recalculated, and both bars and labels animate over one second via `transition()` and `merge()` to accommodate the new element with a slightly narrower band width.

59. D3 Ease Linear

A bar chart displays a dataset of 20 values, initially rendered in blue. Clicking a text prompt triggers a 2-second transition where the bars' heights, positions, and labels animate to a new dataset. The animation uses `d3.transition()` with `.duration(2000)` and `.ease(d3.easeLinear)`, demonstrating linear easing. The SVG elements are created programmatically, with bar positions scaled via `d3.scaleBand()` and `d3.scaleLinear()`, and label positions updated alongside the rectangles.

51. D3 Bar Chart

This is a simple D3.js bar chart that visualizes a numeric dataset of 20 values, displaying each value as a rectangle scaled in height and colored in varying shades of blue. The chart uses an SVG element sized 500 by 100 pixels, with rectangles positioned horizontally and vertically scaled by a factor of four. Each bar is labeled with its corresponding number, rendered in white text. The example demonstrates basic D3 v4.5.0 APIs including `d3.select`, `svg.selectAll`, `.data()`, `.enter()`, and `.attr()`, with a static dataset defined as an array of integers.

Bar Chart

This animated bar chart displays 31 random data points across a linear x-scale and a 0-to-10 y-scale, updating with new values on each button click. Built with D3 v4, it renders SVG axes and bars, using a clip path to contain the body and a merge pattern with transitions to smoothly animate bar positions and heights as data refreshes. The chart is constructed via a reusable `barChart` function that configures margins, scales, and ordinal colors for potential customization.

80. D3 Click

A bar chart displays a dataset of 20 numeric values, rendered as blue SVG rectangles with white value labels. Each bar darkens as its value increases. When a user clicks any bar, the corresponding data value is logged to the browser's developer console. The visualization uses D3 v4.5.0, employing `d3.scaleBand` and `d3.scaleLinear` for positioning and height, with the click event handled via `.on("click", ...)`. The y-axis is implied through bar heights that grow from the bottom, and the chart is static apart from the logging interaction.

Simple bar chart transition

Three bar chart datasets are displayed through a select menu, with animated transitions between value sets using SVG rectangles. The chart shows exiting bars shrinking downward and disappearing, while new and updated bars grow from the bottom to their new heights. The code uses d3.v4’s `d3.transition()` and `selection.merge()` to handle enter, update, and exit states, with a `d3.scaleOrdinal` and `d3.schemeCategory10` for color mapping. Data is hardcoded as arrays of numbers, and the select element triggers `updateBars` on change.
