This example shows how to load and visualize a small CSV dataset as interactive circles in an SVG. The chart displays five data points positioned by their x and y coordinates, with clickable circles that highlight the selected point. Built with React and D3 v7, the App component uses d3.csv to parse the data, scales it with d3.scaleLinear, and renders the visualization through d3.select and selection.join. A custom useContainerDimensions hook tracks the container size via ResizeObserver, enabling responsive scaling of the fixed-domain coordinates.

CV: Loading CSV Data

This example demonstrates how to load and visualize data from a CSV file using React and D3 v7. It renders five circles positioned according to x and y coordinates read from `data.csv`, with interactive click-to-select behavior that highlights the chosen circle. A custom `useContainerDimensions` hook tracks the container size using `ResizeObserver`, while D3's `csv` function parses the data and `scaleLinear` maps data coordinates to screen space. The `join` method efficiently handles circle creation, updating, and removal in the SVG rendering.

This example visualizes CSS named colors as a grid of circles, where clicking any circle displays its corresponding hex value above the SVG. The data is loaded asynchronously from a GitHub-hosted CSV file using the `d3.csv` function within React's `useEffect` hook. Rendering is handled through React components that generate SVG circles, with interaction managed via callback handlers like `handleMouseOver` and `onClick`. The visualization also displays data statistics, including file size, row count, and column count, computed using `d3.csvFormat`.

This example shows a stacked bar chart of time allocation across work sessions, breaking down each session into focused work, interruptions, and recovery percentages. It loads a small CSV file with raw text parsing and renders the data using React with D3 v7 and SVG. The visualization uses d3.stack, scaleBand, and scaleLinear to create the bars, with value labels, axes, and a color-coded legend. A ResizeObserver hook tracks container dimensions to redraw the chart responsively.

Fork of ICE-5: Loading and Parsing CSV Data with D3.js

This example demonstrates how to load and parse CSV data using D3.js within a React framework, rendering an SVG visualization. The code fetches tabular data and maps it to visual elements, including a series of styled paths, rectangles, and ellipses that form a recognizable icon-like shape. It uses D3’s data binding methods to iterate over the parsed rows and attributes like `fill` and `stroke` to style the output. The SVG viewBox and coordinate system are explicitly defined to control the layout, with D3’s `d3.csv` and DOM selection APIs driving the data-to-visual mapping.

This example shows grouped horizontal bars comparing two metrics—"Ermüdungspunkt" (fatigue point) and "Stilkonstanz" (style consistency)—across five image-processing features. The React component loads a local CSV file using d3.csv, parses numeric fields, and renders an SVG chart via d3.scaleBand and d3.scaleLinear. Axis ticks come from d3.axisBottom and d3.axisLeft, with value labels and a color-coded legend appended to the SVG. The chart updates responsively using a ResizeObserver hook.

Fork of ICE-5: Loading and Parsing CSV Data with D3.js

This visualization demonstrates how to load and parse CSV data using D3.js version 7 within a React framework. The page displays a summary of the dataset’s size, row count, and column count in a styled text container, alongside a decorative SVG star and circle graphic. The code uses `d3.csv` to fetch data from a GitHub gist URL, then `d3.csvFormat` to calculate the file size in kilobytes. The example also includes a static inline SVG illustration and an external SVG image, rendered as part of the overall layout.

Fork of loading data with react and d3

This example demonstrates how to load and display CSV data in a React application using D3’s `d3.csv` method. It fetches a dataset of CSS named colors from a GitHub gist and stores the parsed rows in component state via React’s `useState` and `useEffect` hooks. The code includes a commented-out SVG visualization of circles, suggesting potential rendering with React elements, though no visual output is actively rendered. A utility function in `message.js` calculates dataset statistics like file size, row count, and column count using `d3.csvFormat`.

A React and D3 v7 donut chart compares AI consistency (95%) with human variability (5%) in image generation. Each colored arc is rendered using d3.pie and d3.arc generators, with icons and percentage labels positioned via arcGenerator.centroid. Clicking a segment toggles an info panel displaying category details while dimming inactive arcs. Data is hardcoded in App.jsx, and the chart responds to container resize events through a ResizeObserver hook.
