D3 Bar Chart (Animations)

27. D3 Bar Chart Teal

This bar chart displays a static dataset of 20 numeric values, rendered as teal-colored rectangles in an SVG container. The code uses D3.js version 4.5.0 to bind the array of numbers to SVG `rect` elements, calculating each bar’s x-position, width, and height based on the dataset length and value. The bars are vertically scaled by a factor of 4, with a 1-pixel padding between them. The chart does not include axes, labels, or interactivity, focusing solely on the basic bar-encoding technique.

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.

D3 Bar Chart Rects

This example demonstrates a simple bar chart built with D3.js, where an array of twenty numeric values is visualized as a series of teal, inline-block rectangles. The chart uses D3's selection and data-binding API (`d3.select`, `.data`, `.enter`, and `.append`) to dynamically create `div` elements with a CSS class. Each bar’s height is set via the `.style` method, multiplying the data value by a fixed factor to produce a pixel height, resulting in an animated rendering of the dataset.

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.

30. D3 Bar Chart Aligned

This example displays a static bar chart of 20 numeric values using D3 v4, with each bar rendered as an SVG rectangle and labeled with its corresponding data value in white sans-serif text centered within the bar. The chart uses a fixed SVG width of 500 pixels and height of 100 pixels, with bar heights scaled by a factor of four and a one-pixel padding between bars. Each rectangle’s fill color is a blue gradient calculated from its data value, and the labels are positioned inside the bars using `d3.selectAll` with data binding and `.attr` methods.

D3 bar chart without data-binding

A static SVG bar chart displays twenty purple rectangles of varying heights, representing an inline array of numeric values. The code uses D3 v4 scales, `d3.scaleLinear`, to map data values to pixel heights and positions, though it does not use the data join's update or exit selections. Bars are appended via `selectAll("rect").data(data).enter()`, with each rectangle’s height and y-coordinate computed from the scale; the x-position is calculated manually from the index. No interaction or animation is present, and the chart is rendered with fixed SVG dimensions.

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.

28. D3 Bar Chart Blues

A bar chart displays a fixed dataset of 20 numeric values in a viewport 500 pixels wide and 100 pixels high. Each bar’s height is proportional to the data value, scaled by a factor of four, and its horizontal position is computed from the array index and overall width. The bars are rendered as SVG rectangles using the D3.js v4.5.0 library, with a dynamic fill color that transitions from dark to lighter blue based on the data value. This example demonstrates simple data-driven styling without any animation or interactive elements.
