A colored bar chart displays a dataset of numeric values as vertical bars, with color mapping from green through orange to red via a `d3.scaleLinear` domain of 0 to 110. React state management allows the user to increment, filter (values ≤ 50), or randomly append data through buttons, triggering `useEffect` updates. The SVG is rendered using `scaleBand` for x-positioning, `scaleLinear` for y-scaling, and D3 v5 axes. Bars animate on transitions, and mouseenter events create tooltips with D3 text elements that fade in.

Bar Chart

This example shows a bar chart with six labeled bars (a–f) of varying heights, rendered as an SVG in a React environment using D3 v3. The code defines a band scale for the horizontal axis, a linear scale for the vertical axis, and draws axes with tick marks. It uses D3’s selection and data-join pattern (`selectAll`, `data`, `enter`) to create a `rect` for each data point, with bars filled in steel blue. The data is hardcoded in the script, with margins and padding configured around the 500-by-500 pixel canvas.

Bar chart

This example renders a simple bar chart using D3 v5 with SVG output within a React framework. Six hardcoded data values are displayed as vertical bars, with bars colored red for values 80 or higher and gray for lower values. Each bar’s height is twice its data value, and the corresponding number labels each bar. The chart uses D3’s `select`, `append`, and `attrs` methods to construct and style the SVG rectangles and text elements, with the page structured by an HTML file loading the D3 libraries and the chart script.

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.

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()`.

[04] Animated bar chart - Using React Hooks with D3

This example shows an interactive animated bar chart where users can increment, decrement, filter, or append values to a dataset, with bars flipping vertically and transitioning smoothly to new heights. Built with React Hooks and D3 v5, it uses `scaleBand` for the categorical x-axis, `scaleLinear` for y and color interpolation, and `selection.transition()` to animate bar heights and fill colors based on a clamped color scale. The SVG rendering uses `transform: scale(1, -1)` to flip bars, with axes positioned via `axisBottom` and `axisRight`.

Lets Make a bar chart with D3 Format

This example shows a bar chart that visualizes a static array of seven numeric values using blue rectangular bars with red value labels. The code uses D3 v5 to create SVG rectangles and text elements, with bar dimensions and positions calculated from the dataset. Bar heights map directly to data values, while labels sit slightly above each bar. The chart uses a fixed SVG viewport of 500 by 300 pixels, with bars spaced using a computed width and translate transform.

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.
