This example shows a horizontal bar chart of the top 10 countries by population in 2020, with rectangular marks colored teal and a formatted axis labeling values in billions. Built with React and D3 v5, it uses scaleBand for the y-axis, scaleLinear for the x-axis, and separates chart elements into reusable components like AxisBottom, AxisLeft, and Marks. Population data is loaded from a CSV file using d3.csv, and the SVG is rendered entirely through React.

Making a Bar Chart with React & D3

This example shows a horizontal bar chart of the top 10 countries by 2020 population, with each bar representing a country’s estimated population in millions. The visualization is built by combining React for component rendering with D3 utilities for data loading and scales. The code uses `d3.csv` to fetch the dataset, `d3.scaleBand` for the categorical y-axis positioning, and `d3.scaleLinear` for the continuous x-axis range. Bars are rendered as SVG `<rect>` elements inside a React component, with the chart’s width and height fixed at 960 by 500 pixels.

Bar chart with react and D3

This example displays a horizontal bar chart of the top ten countries by population for 2020, using React to manage state and render the SVG, while D3 provides the scales and data loading. The chart uses `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the y-axis categories, and `d3.csv` to fetch data from a GitHub Gist. Axis labels and tick marks are generated manually with React components and D3’s tick function, with no additional libraries beyond the core React 16.9 and D3 v5 APIs.

Bar Chart

This example shows a horizontal bar chart of the top 10 countries by population, with each bar’s length representing the 2020 population estimate. The bars are rendered as SVG `<rect>` elements using React, with scales from `d3.scaleBand` for the country categories and `d3.scaleLinear` for the population values. Data is loaded asynchronously from a CSV file using `d3.csv`, which parses the population column as numbers before the chart updates. The visualization combines D3’s data-loading and scaling utilities with React’s declarative component structure.

Making a Bar Chart with React & D3

This example shows a horizontal bar chart displaying the top 10 countries by 2020 population, using React for component structure and D3 for scales. It renders SVG rectangles with widths proportional to population values, using `scaleBand` for the y-axis and `scaleLinear` for the x-axis. Data comes from a CSV file loaded via `d3.csv`, and React’s `useState` and `useEffect` manage the asynchronous data fetching. The visualization appears once data is loaded, otherwise showing a loading message.

Making a Bar Chart

This example presents a horizontal bar chart of the top 10 countries by population in 2020, using data loaded from a CSV file. The visualization is built with React, which renders SVG elements, while D3 utilities handle data processing and scales. The code uses `scaleBand` for the categorical country axis and `scaleLinear` for the population value axis, mapping data to rectangle dimensions. The chart loads data via `csv` and updates reactively once the data arrives, displaying "Loading..." until then.

Making a Bar Chart with React & D3

This example shows a horizontal bar chart of population data for the top 10 countries in 2020, rendered as SVG using React components. It loads data from a CSV via `d3.csv` in a custom `useData` hook, then uses `scaleBand` for the categorical y-axis, `scaleLinear` for the numeric x-axis, and `format` to abbreviate tick labels (e.g., converting "G" to "B"). The chart includes custom axis components and rect marks with built-in tooltips.

Making a Bar Chart

This example shows a horizontal bar chart of the top 10 most populous countries, with population values on the x-axis and country names on the y-axis. It uses D3 v6’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` APIs within a React-free SVG rendering. The data is loaded from a CSV file and parsed by multiplying the population column by 1000. Grid lines are drawn via tick size customization, and the left axis’s domain and tick lines are removed for a cleaner look.

Bar Chart Creation

This example shows a horizontal bar chart of the top 10 most populous countries in 2020, using a D3 scaleBand for the y-axis and a scaleLinear for the x-axis. Built with React, it loads CSV data via d3.csv and renders SVG rectangles for each bar. The chart includes formatted population labels on the bottom axis using d3.format, with axis components defined in separate React files. The x-axis label, axis ticks, and bar styling are all customized through CSS classes.
