This example displays a simple horizontal bar chart built with React and rendered as SVG using D3 v6. Each bar’s width is proportional to the person’s age from the local CSV file `nameage.csv`, with bars spaced vertically at 50-pixel intervals. The code loads the data via `d3.csv`, selects the body, appends an 800x800 SVG canvas, and binds the dataset to `rect` elements whose `width` attribute is computed as `d.age * 20`. All bars are filled with cyan, and the chart includes no axes or labels, focusing purely on raw geometric encoding.

D3 practice

A single row of six vertical bars displays categorical values from a fixed array. The bar heights correspond to the numeric data, and each bar is positioned with a uniform width and small spacing between bars. The visualization is built with D3 v5’s selection and `.data()` methods, appending SVG `rect` elements to an `<svg>` element in a React-free HTML page. The chart’s dimensions and bar positions are explicitly set, while the CSS removes page scrolling by positioning the body absolutely.

HTML Starter

This example renders a horizontal bar chart of country populations using SVG and React. The code loads population data from a CSV file with d3.csv and scales the values using d3.scaleLinear and d3.max to map population counts to pixel widths. It sets up an SVG canvas with fixed dimensions and prepares scales for the axes, though the actual chart bars and axes are not fully drawn in the shown code. The visualization uses d3.v5 within a React framework, with the HTML page linking to the D3 library via a CDN.

Basic Bar chart

This example presents a basic bar chart built with D3 v5 and React, rendering to SVG. The chart displays a static dataset of five values as vertical bars, with bar heights proportional to the numbers. The code defines a 500x500 SVG canvas, applies a padding of 2 pixels between bars, and positions each rectangle using a calculated x coordinate. D3’s data join pattern (selectAll, data, enter, append) creates the rectangles, while attributes like width, height, and y are set via arrow functions derived from the dataset.

Making a bar chart with React & D3

This example demonstrates how to build a bar chart using React to render SVG elements and D3 to load and parse data. The visualization fetches population data from a CSV file via `d3.csv` and displays it as a series of rectangles, with React’s `useState` and `useEffect` managing the asynchronous data loading. D3 v6 and React 17 are used together, with the chart showing a loading message until the dataset is ready. The SVG-based chart currently renders blank rectangles without positional or size encodings, highlighting the integration of React’s declarative component model with D3’s data utilities.

Bar chart Testing

This example displays a horizontal bar chart of Indian population data by year, using React to render SVG elements. D3’s `scaleLinear` maps population counts to bar widths, while `scaleBand` positions bars along the y-axis and `scaleOrdinal` assigns colors from `schemeDark2`. The code fetches CSV data via D3’s `csv` method, parses the first five entries, and draws axes with SVG lines and ticks. Both D3 v7 and React 18.2 are used, with the visualization mounted through `ReactDOM.createRoot`.

Making a Bar Chart

This example demonstrates how to build a horizontal bar chart from scratch using D3 v5 in a React framework. The visualization displays population data for ten countries, with bars rendered as SVG rectangles scaled linearly by population and positioned using a band scale for country names. The code explicitly uses D3’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` functions, reading data from a CSV file. Axes are appended to a grouped SVG element, and bar heights are determined by the band scale’s bandwidth.

Making a bar Chart

This example displays a horizontal bar chart of country populations, with bars scaled proportionally to population values and country names on the vertical axis. It uses D3 v5 within a React-like structure, loading data from a local CSV file and rendering to SVG. The code employs D3’s `scaleLinear` for the numeric axis, `scaleBand` for categorical spacing, and `axisBottom` and `axisLeft` to generate tick marks and labels.

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.
