This example shows a horizontal bar chart ranking the top 10 countries by 2020 population, with bars drawn as SVG rectangles inside a React component. The chart uses `d3.csv` to load UN population data from a gist URL, then transforms it with `scaleBand` for the y-axis and `scaleLinear` for the x-axis. The React app manages the data asynchronously via `useState` and `useEffect`, rendering a loading message until the data arrives. The visualization is a simple one: yellow bars extend from the left, sized proportionally to each country’s population.

Fork of Fork of react bar 2 margins

This bar chart displays the top 10 countries by 2020 population from a UN dataset, using a horizontal bar layout with yellow circular background elements. The React application fetches CSV data via d3.csv, scales the bars with d3.scaleLinear and d3.scaleBand, and renders the SVG inside a viewBox with margins. The visualization loads using React 17, D3 v7, and includes a background circle component that acts as a decorative frame.

Fork of Fork of Fork of Make a bar chart with react and d3

This example shows a horizontal bar chart ranking the top 20 countries by 2020 population, rendered as SVG rectangles in React. The code loads data from a CSV of UN population statistics using `d3.csv`, then uses `scaleBand` for the categorical country axis and `scaleLinear` for the population values. React’s `useState` and `useEffect` manage the asynchronous data loading, while JSX maps each country to a `<rect>` element. The chart updates purely through React’s render cycle, with D3 providing only scales and data parsing utilities.

Fork of Refactored Bar Chart

This example visualizes the top 10 most populous countries as horizontal bars, using SVG rendering within a React app. The chart displays population values against country names, with no axes initially, though it includes bottom and left axis components built from D3 scales. Data comes from the UN World Population Prospects 2019 CSV, loaded via `d3.csv`. The code uses React hooks (`useState`, `useEffect`) and D3 v5 functions like `scaleBand` and `scaleLinear` to position marks and axes, with all rendering handled by React elements.

Fork of Rendering data with React and D3

This example shows a horizontal bar chart of the top 10 countries by 2020 population, rendered as SVG rectangles. It loads UN population data from a CSV file using `d3.csv`, then maps the data to React state with `useState` and `useEffect`. The chart uses `d3.scaleBand` for the y-axis country categories and `d3.scaleLinear` for the x-axis population values, with each bar’s width and position computed from these scales. React renders the SVG elements, while D3 handles data parsing and scaling.

Fork of Fork of Fork of Rendering Data With REACT

This example displays a horizontal bar chart of the top ten countries by population, according to the UN Population 2019 dataset. It shows both how D3 can load and scale data and how React manages the rendering state asynchronously. The code loads data with `d3.csv`, maps values using a scaleBand for the categorical country axis and a scaleLinear for the numeric population axis, and renders `d3.rect` SVG elements. React’s `useState` and `useEffect` hooks control the data loading and display a loading message before the chart appears.

Bar Chart with React

A bar chart displays the top 10 countries by 2020 population, sourced from a UN Population CSV loaded via `d3.csv`. The React component uses `useState` and `useEffect` to fetch and store data, then renders an SVG with `d3.scaleBand` for countries on the y-axis and `d3.scaleLinear` for population on the x-axis. Gridlines and tick labels are generated from `xScale.ticks()`, while each bar is a `<rect>` with fill opacity and stroke styling.

Fork of Fork of Fork of Fork of Rendering Data With REACT

This example displays a horizontal bar chart comparing the 2020 populations of the top ten countries from a UN population dataset loaded via `d3.csv`. The visualization uses React state to store the parsed data, and renders SVG elements dynamically. D3’s `scaleBand` and `scaleLinear` position bars and axis ticks, while React’s `useEffect`, `useState`, and `useCallback` manage data fetching and component updates. Axes and gridlines are generated using `xScale.ticks()`, with text labels for both countries and population values.

Fork of Population Bar Chart Basic

This example displays a horizontal bar chart of the top 10 countries by population for 2020. It uses React hooks to load and store the data, which comes from a CSV file of United Nations population estimates. The chart renders as SVG rectangles, with scales created using `d3.scaleBand` and `d3.scaleLinear` to map country names and population values to pixel positions. The `d3.csv` method parses the data, and the `xScale` and `yScale` dimensions are set to fixed width and height values.
