This example renders a horizontal bar chart of country populations using a React-free HTML page. It loads data from data.csv via `d3.csv`, then scales the values by 10 million. The visualization uses `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the y-axis, and `d3.axisLeft` and `d3.axisBottom` to draw the axes. Bars are appended as SVG `rect` elements within a grouped `<g>` transform, with height set by `yScale.bandwidth` and width proportional to population.

Fork of Fork of data visulization

This example shows a horizontal bar chart of country populations, using bar length to encode population values and vertical position to encode country names. The visualization renders as SVG with steel-blue bars and axes, drawing from a CSV file that is loaded asynchronously and preprocessed by multiplying population values by 1,000. The code uses D3 v6 APIs including `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, `axisBottom`, and `max` within a React context, though the primary rendering is handled directly with D3 selections and SVG elements.

Fork of Rendering Data with React & D3

This example shows a horizontal bar chart of the ten most populous countries in 2020, using a bar width proportional to each country’s population. It loads CSV data from a GitHub gist via `d3.csv`, then maps each row’s population string to a number. The React component uses `useState` and `useEffect` to fetch and store the data, while `d3.scaleBand` and `d3.scaleLinear` position and size the rectangles. React renders the final SVG, with each country’s name on the y-axis and its population scaled along the x-axis.

Fork of Rendering Data with React & D3

This example shows a horizontal bar chart of 2019 population data for various countries, with bar lengths proportional to each country's population and bars stacked vertically without spacing. The visualization is built using React and D3 v5, where D3’s `scaleBand` and `scaleLinear` map country names to y-coordinates and population values to bar widths within an SVG canvas. Data is loaded asynchronously from a CSV file via D3’s `csv` function, and the React component uses `useEffect` and `useState` to fetch and render the chart once the data arrives.

Fork of Rendering Data with React & D3

This visualization displays a horizontal bar chart of 2020 population estimates for countries, rendered as SVG using React and D3 v5. It loads CSV data from a GitHub gist via D3’s `csv` utility, then maps the parsed data to `rect` elements. React handles the UI state and component structure, while D3’s `scaleBand` and `scaleLinear` position the bars, and `max` computes the domain. The visualization updates once the asynchronous data fetch completes, initially showing a loading message.

Fork of HTML Starter

This example shows a horizontal bar chart of population data for 20 countries from 2010, using React with D3 v5 for scales and axes. It loads CSV data via `d3.csv` and renders SVG elements with `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis. The chart includes formatted tick labels using `d3.format` and displays a custom tooltip on each bar through SVG `<title>` elements. The visualization demonstrates a basic data-loading workflow with `useEffect` and `useState`.

Fork of Fork of Loading Data with React & D3 in Bar Chart

This example demonstrates a horizontal bar chart that displays population data for ten countries, rendered as SVG elements within a React component. The chart uses D3’s `scaleBand` and `scaleLinear` to position bars and axes, while gridlines and tick labels are generated with `xScale.ticks()`. Data is loaded asynchronously from a CSV file using `d3.csv` and stored in React state via the `useEffect` hook. A separate `message.js` module computes a data summary string included in the display.

Fork of Rendering data with React

This example shows a horizontal bar chart of the top 10 most populous countries in 2020, using D3 utilities to load and scale the data and React to render the SVG bars. The code uses `d3.csv` to fetch population data from a gist, `d3.scaleBand` for the categorical y-axis, and `d3.scaleLinear` for the quantitative x-axis. Each country is drawn as a React `<rect>` component within an SVG, with bar widths proportional to population values.

Fork of Rendering data with React & D3

This example shows a horizontal bar chart of the top ten countries by population in 2020, using a combination of React and D3. The chart displays population values as proportional bar widths, with axis ticks and country labels generated from the loaded CSV data. React manages the component state and lifecycle through hooks like `useState` and `useEffect`, while D3’s `scaleBand`, `scaleLinear`, and `max` functions handle scaling and data processing. The visualization renders as SVG, with bars and text elements created declaratively in JSX.
