This example displays a horizontal bar chart of UN population data for 2019, using React state to manage the asynchronous loading of CSV data via D3’s `csv` utility. The bars are rendered as SVG `<rect>` elements whose widths map to population values through `d3.scaleLinear`, while country names are positioned using `d3.scaleBand`. The visualization shows a loading message until the data arrives, then renders the chart with a fixed size of 960×500 pixels. D3 v5 and React 16.9 are loaded via CDN, and the data is fetched from a gist hosted by Curran Kelleher.

AI-generated description

A program that loads in some data about CSS named colors using D3 utilities, and uses React state to keep track of the data.

Fork of Rendering Data with React & D3

This example renders a horizontal bar chart of UN population data for 2020 using React and D3 v5. It loads the CSV file with `d3.csv`, parses the population column, and stores the result in React state via the `useState` and `useEffect` hooks. The visualization uses `scaleBand` and `scaleLinear` to map countries and populations to SVG `rect` elements, with React’s declarative rendering driving the SVG output. While loading, it displays a large “Loading…” message before the chart appears.

Fork of Loading Data with React & D3

This example shows a horizontal bar chart of the top 10 most populous countries in 2020, based on UN population data loaded from a CSV file. The visualization uses React state to manage the asynchronous data loading, with the `useEffect` hook triggering a D3 `csv` request. The chart renders SVG rectangles whose widths are scaled by population using `scaleLinear`, while country names are positioned along the y-axis with `scaleBand`. The code demonstrates integrating D3 utilities for data fetching and scaling within a React component architecture.

Fork of Loading Data with React and D3

This bar chart displays the 2020 population of various countries, sourced from a CSV file hosted in a GitHub gist. The React application loads the data asynchronously using D3's CSV parser, then configures a band scale for the categorical country axis and a linear scale for the quantitative population axis. Rendered as SVG rectangles via ReactDOM, each bar's width encodes the population value, with a loading message shown while the data is pending.

Fork of Loading Data with React & D3

This example shows a bar chart of the top 10 countries by 2020 UN population estimates, loaded asynchronously from a CSV file. The chart uses D3 scales (scaleBand and scaleLinear) to map country names and population values to SVG rectangles, with grid lines and tick labels generated from the x-axis scale. React manages the component state, fetching data with the useEffect hook and rendering the SVG markup directly. The visualization demonstrates a simple integration of React for UI state and D3 for data-driven SVG geometry.

This visualization displays UN population data for 2020 as a horizontal bar chart, where each bar’s length corresponds to a country’s population. The chart is built with React and rendered as SVG, using D3’s `csv` loader, `scaleBand` for the y-axis, and `scaleLinear` for the x-axis. The example demonstrates how D3 utilities handle data loading and scaling, while React manages the component state and maps each data row to an SVG `<rect>`.

Fork of Rendering DATA with React & D3

This example shows a horizontal bar chart of United Nations population data for 2020, with each country represented as a rectangle whose width corresponds to its population. The visualization uses React state management to load and store the dataset via `useState` and `useEffect`, while D3 v6 utilities such as `csv`, `scaleBand`, `scaleLinear`, and `max` handle data parsing and scaling. The bars are rendered as SVG `<rect>` elements, mapped from the data array using React's declarative JSX syntax. A loading state displays "Loading.." until 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 Rendering Data with React & D3

This example shows a horizontal bar chart of the top 10 countries by 2020 population from a UN dataset, loaded via `d3.csv`. React state manages the fetched data, while `d3.scaleBand` and `d3.scaleLinear` map country names and population values to SVG rectangles. The visualization renders with React’s declarative JSX, using `d3.max` for the domain and the `useEffect` hook to trigger the asynchronous data load. The bars update on data arrival, replacing a simple loading text.
