A bar chart displays 20 vertical bars whose heights and blue color intensities correspond to values in a static array. Clicking the text prompt replaces the dataset with 20 new random integers between 0 and 24, then animates the bars and their value labels using `transition` with `delay` and `duration`. The chart uses `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, with SVG `rect` and `text` elements. Data is updated via a click handler on a paragraph element.

D3: Transitioning to randomized data values

This example shows a bar chart with value labels that randomize each time the user clicks on the text prompt above it. Initially, a fixed dataset of twenty values is rendered as SVG rectangles with a blue color scale and overlaid text labels. Upon clicking, the D3 transition API animates each bar's new height, fill color, and label position with a staggered delay based on its index, using `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis. The original code was adapted from the book *Interactive Data Visualization for the Web* and updated to work with d3.v4.

15. D3 Power of Data Random

A dynamic bar chart displays 25 randomly generated values as vertical teal bars. The visualization uses D3.js version 4.5.0 to bind an array of random numbers between 0 and 30 to HTML div elements, setting each bar’s height proportional to its data value. The animation updates the bar heights, demonstrating how D3 can render and update data-driven visualizations.

66. D3 Delay Dynamic Scaled Few

A dynamic bar chart displays ten data values as vertical bars with numeric labels. Users can click a text prompt to trigger a one-time update to a new dataset. The chart uses D3.js version 4.5.0 with `scaleBand` for the x-axis, `scaleLinear` for the y-axis, and `transition().delay()` to create a staggered animation effect. As the data updates, both the rectangle heights and label positions animate sequentially, with fill colors shifting from dark to light blue based on the new values.

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.

74. D3 Adding Values

Clicking the text at the top adds a new random value to a dataset, causing a bar chart to update with a smooth transition. The example demonstrates the D3 data join pattern, using selections and `merge` to handle entering and updating rectangles. It employs `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and SVG transitions over 500 milliseconds to animate the bars and their labels.

64. D3 Delay Dyanmic

This example shows a bar chart that updates its values when the user clicks on a text prompt. The chart displays a sequence of numeric values as vertical bars, each labeled with its value. The visualization uses D3.js version 4.5.0 to render the chart as SVG elements. Upon clicking, the bars and labels transition to new data with a staggered delay, where each subsequent element waits an additional 100 milliseconds before starting its 500-millisecond animation. The code uses D3's `scaleBand`, `scaleLinear`, and `transition().delay()` API to manage the layout and animated updates. The data is a hardcoded array of twenty numbers.

56. D3 Duration

A bar chart displays twenty data values as vertically oriented rectangles, each labeled with its numeric value. Clicking the prompt text triggers a one-time update with a new dataset. The visualization uses D3 v4.5.0 to construct an SVG scene with `d3.scaleBand` for x-axis positioning and `d3.scaleLinear` for bar heights. The update applies a `transition` with a controlled `duration` of 1000 milliseconds, smoothly animating the rectangles' y-coordinates, heights, and fill colors. Text labels update instantly without transition.

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.
