This example demonstrates how a bar chart can transition between datasets using D3.js version 6. It fetches vehicle registration data from the RDW Open Data API, counts cars by color per year, and displays the most popular colors for 2017. Users toggle between 2016 and 2017 datasets via radio buttons, triggering animated updates with `transition()` and `duration()`. The chart uses `d3.scaleBand` and `d3.scaleLinear` for axes, with an SVG rendering approach and a button-based interaction pattern.

Barchart met RDW Data v6

Three bar charts of synthetic categorical data react to two toggle buttons labeled "Taxis" and "Personenautos." Clicking either button triggers an animated update that linearly transitions the bar heights over one second, swapping between the two predefined datasets. The visualization uses D3 v5, building the SVG with `d3.scaleBand`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft`, while a custom `update` function leverages `.transition().duration()` to smoothly change rectangle geometries.

Barchart met RDW Data v6

This bar chart displays three categorical values for two datasets, comparing taxis and passenger cars. Two buttons switch between the datasets, triggering a smooth animated transition of the rectangular bars. The visualization uses D3.js version 5 with SVG rendering, leveraging `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and the `.transition()` method for animations. The chart initializes with the passenger car data and updates bar positions, heights, and fill colors dynamically.

Bar chart with D3.js

This bar chart displays the distribution of car colors as percentages, using a dataset from a GitHub gist. Built with D3.js v5 in a React component, it renders as an SVG with animated bar interactions. The `d3.scaleBand` and `d3.scaleLinear` functions handle the axes, while `d3.axisBottom` and `d3.axisLeft` create the ticks. Hovering over a bar triggers a transition that highlights the bar and draws a red dashed line, showing the hovered value’s position, with divergence text displayed via `d3.selectAll` and `.transition()`.

Barchart met RDW Data v6

Two interactive bar charts present data for three groups (A, B, C) across two datasets. Users switch between the "Taxis" and "Personenautos" datasets via buttons, triggering a smooth transition animation that updates the bar heights. Built with D3 v5, the visualization uses `d3.scaleBand` and `d3.scaleLinear` for axes, while the `transition()` method animates rectangle attributes over one second. SVG rendering handles the graphics, and the update function leverages D3's enter/merge/exit pattern to efficiently redraw bars.

Barchart met RDW Data v6

Two bar charts share a single SVG canvas, displaying categorical values for groups A, B, and C. Users switch between the "Taxis" and "Personenautos" datasets by clicking buttons, which triggers a D3 v5 transition that smoothly animates the rectangular bars to their new heights over one second. The visualization uses `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `selection.merge` with `.transition().duration()` to update existing SVG rect elements. Static axes and a teal fill style (via CSS) frame the animated data comparison.

D3 Bar Chart

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.

Bar chart with D3.js

This bar chart visualizes the distribution of colors in a sample dataset, with each bar representing a color percentage and labeled with its value. The D3.js v5 example uses an SVG rendering approach with interactive hover effects that highlight the selected bar, display a red dashed threshold line, and show divergence percentages between the hovered color and others. Built with `d3.scaleBand` and `d3.scaleLinear` for axes, the chart includes grid lines, a title, and axis labels, with animations driven by `transition` for bar highlighting and opacity changes on mouse events.

Basic Bar Chart Animation Test (Fixed Data)

This example demonstrates an interactive bar chart where users can dynamically alter the dataset through buttons that increase, decrease, filter, or append random values. The bars animate their height and color transitions over one second, with hover tooltips displaying each bar's value. Built with React and D3 v5, the visualization uses `scaleBand` and `scaleLinear` for axes, a `linearGradient`-like color scale mapping values to a red-to-green range, and D3's `.transition()` method to smooth updates to the SVG elements.
