Forked from Fork of Rendering Data with React & D3

This example shows a horizontal bar chart of student marks, ranking the top 10 students by their scores. The visualization uses React hooks (`useState`, `useEffect`) to load CSV data via `d3.csv`, then renders SVG rectangles scaled with `d3.scaleBand` and `d3.scaleLinear`. Axes are drawn manually using mapped tick values rather than D3 axis generators, with React creating the SVG elements. The chart updates reactively as data loads, displaying a loading message until the CSV arrives from the GitHub gist URL.

This visualization displays a horizontal bar chart comparing student marks, using a dataset loaded from a CSV file and limited to the first 10 students. The chart renders as an SVG, with blue bars representing each student’s score on a linear scale, while a band scale positions the student names on the y-axis. The code combines React hooks for state management and data loading with D3 utilities such as `csv`, `scaleBand`, `scaleLinear`, and `max` to compute scales and render tick marks and rectangles.

Fork of Rendering Data with React & D3

This example shows a bar chart of the top ten countries by population for 2020, rendered as an SVG using React and D3. It loads CSV data from a GitHub gist with d3.csv, then maps the data to scaleBand and scaleLinear scales for country and population axes. React components render the axes and rectangles via SVG, and a d3-based tick system draws gridlines.

Fork of Rendering Data with React & D3

This example renders a horizontal bar chart of project volumes using React and D3. The code loads a CSV file via the `d3.csv` utility, then maps the data to SVG rectangles positioned with `d3.scaleBand` and scaled with `d3.scaleLinear`. It uses React's `useState` and `useEffect` hooks to fetch and manage the data, and renders axes and marks through custom components. The chart displays, for each project, a bar whose width corresponds to its planned final volume, with hover tooltips via an HTML `<title>` element.

Fork of Render Data with React & D3

This example shows a horizontal bar chart of the top 10 countries by 2020 population, rendered as SVG rectangles sized by population. The app uses React state and hooks to fetch a CSV from a gist, parse it with `d3.csv`, and map the data to scales via `d3.scaleBand` and `d3.scaleLinear`. The chart updates reactively when data loads, displaying a simple loading message until then.

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.

Fork of Fork of ICE-6: Rendering Marks and Channels with React & D3

This example presents a horizontal bar chart ranking the top 10 most populous countries in 2019, loaded from a CSV file using d3.csv. The React component renders SVG marks (rectangles) whose widths and positions are scaled by d3.scaleLinear and d3.scaleBand, with custom tick labels and gridlines drawn manually. The code uses React hooks like useState and useEffect to manage asynchronous data loading, and d3.scaleLinear, d3.scaleBand, d3.max, and d3.format for scales and formatting.

Fork of Rendering Data with React and D3

This example renders a bar chart of the top 10 countries by 2020 population using React and D3. It loads CSV data from a remote URL with d3.csv, then uses d3.scaleBand and d3.scaleLinear to map countries and population values to SVG rectangles. The visualization highlights a hybrid approach where D3 handles data loading and scales while React manages the SVG component structure. A commented-out section shows an alternative radial burst layout using d3.pie and d3.arc, though the active code uses a simple horizontal bar format.

Fork of Rendering Data with React

This example shows a horizontal bar chart of the top 10 countries by population as of 2020, using React to render SVG rectangles. The chart loads CSV data with `d3.csv` and use `d3.scaleBand` and `d3.scaleLinear` to map countries and population values to screen coordinates. The data is fetched asynchronously via `useEffect`, stored in React state, and displayed after a brief "Loading..." message. React’s `useState` and `useCallback` manage the data flow, while `d3.max` determines the scale domain.
