This example shows an interactive bar chart of letter frequencies from a CSV file, rendered in React with D3.js. The visualization updates responsively to window resizing via ResizeObserver and allows hover to change bar color and click to select or deselect bars. The code demonstrates a modular architecture where React manages state and component lifecycle, while D3 handles SVG rendering, scales, and axes through its `scaleBand`, `scaleLinear`, and `axisBottom`/`axisLeft` APIs.

AI-generated description

React & D3 Vibecoding Starter

This viz serves as a starter example specifically designed for "Vibecoding" - a workflow where you ask AI to edit and enhance your code. It provides a simple yet functional foundation that demonstrates React and D3 working together. The reason it works so well with AI is because it's broken down into lots of small files, and uses well known patterns.

Key Features

  • AI-Friendly Structure: Organized in a way that makes it easy for AI to understand and modify
  • Responsive Visualization: Automatically adapts to window size changes using ResizeObserver
  • Interactive Elements:
    • Hover interactions that change bar colors
    • Click interactions that select/deselect bars
  • Data Loading: Demonstrates how to load and process data from CSV files
  • Component Architecture: Clean separation between React for state and D3 for DOM manipulation

How It Works

The application follows a clean pattern:

  1. React manages the component lifecycle and state
  2. D3 handles the SVG rendering and visualization logic
  3. The main visualization updates in response to state changes
  4. Interactive elements respond to user input (hover, click)

This structure makes it easy to ask AI to:

  • Change the visualization type
  • Add new interactive features
  • Modify the styling and appearance
  • Implement more complex data processing

Getting Started with Vibecoding

To use this starter with AI:

  1. Fork this viz
  2. Understand the basic structure (React app with D3 visualization)
  3. Ask the AI to modify if by clicking "Edit with AI"
  4. The AI can analyze the code structure and make appropriate changes
  5. If it messes up, click "Revision History", click on the previous revision, then click "Restore to this version"

Built with React and D3.js - perfect for experimenting with AI-assisted coding!

Fork of React & D3 Vibecoding Starter

This example shows an interactive bar chart of letter frequencies loaded from a CSV file. D3 v7 parses the data with `d3.csv`, while React manages the component state and a `ResizeObserver` tracks container dimensions. Clicking a bar toggles its highlight by updating React state, which re-renders the SVG with adjusted fill and opacity. Axes are created with `d3.axisBottom` and `d3.axisLeft`, and scales using `d3.scaleBand` and `d3.scaleLinear`.

Fork of React & D3 Vibecoding Starter

This example shows a simple bar chart of letter frequencies from a local CSV file. The bars are interactive, so clicking one toggles its selection, highlighting it in a darker color while dimming the others. Built with React and D3.js v7, it uses a declarative `join` pattern to render the SVG elements, `scaleBand` and `scaleLinear` for the axes, and a `ResizeObserver` in React to make the chart responsive to container size changes.

Fork of React & D3 Vibecoding Starter

This example demonstrates a clean, interactive bar chart built with React and D3.js (v7). It visualizes a small dataset, showing the frequency of letters from a CSV file, with bars for each letter. The chart allows users to click on individual bars to highlight and dim others, creating a selection state. It is built by combining React's component model for state management and DOM control with D3's `scaleBand`, `scaleLinear`, `axisBottom`, and `axisLeft` APIs for rendering and layout. The visualization is fully responsive, using a `ResizeObserver` to recalculate dimensions.

Fork of React & D3 Vibecoding Starter

This example shows a bar chart of letter frequencies from a small CSV dataset. A React component manages the chart's container and state, while D3 v7 functions handle the core rendering: `scaleBand` and `scaleLinear` create the axes, `axisBottom` and `axisLeft` draw them, and `renderBarElements` builds the interactive bars. Clicking a bar toggles its selection, changing its fill color and the opacity of others. The chart is responsive, using a `ResizeObserver` to update dimensions.

Fork of React & D3 Vibecoding Starter

This example shows a simple bar chart of letter frequencies from a CSV file, with interactive bars that highlight a selected letter. Built with React 19 and D3 v7, it uses a ResizeObserver to track container dimensions, d3.csv to load data, and d3.scaleBand/d3.scaleLinear for scales. Clicking a bar toggles its selection, dimming other bars via opacity and fill changes.

Fork of React & D3 Vibecoding Starter

This example shows a simple bar chart of letter frequencies from a small CSV dataset. The chart uses a React component with hooks and a ResizeObserver for responsive dimensions. D3’s scaleBand and scaleLinear create the scales, while axisBottom and axisLeft render axes with gridlines. Clicking a bar toggles a selected state, changing its fill and opacity through transitions. The code integrates D3 selections with React state management, using modular rendering functions for the SVG, title, bars, and data loading.

Fork of React & D3 Vibecoding Starter

This example shows an interactive bar chart of letter frequencies from a CSV dataset. The visualization renders seven bars with rounded corners and gridlines, where clicking a bar highlights it and dims the others. Built with React and D3 v7, it uses `scaleBand` and `scaleLinear` for scales, `axisBottom` and `axisLeft` for axes, and a `ResizeObserver` in a custom `useDimensions` hook to handle responsive sizing. D3's data joins update the bars, with click handlers managing selection state through React's `useState`.

Fork of React & D3 Vibecoding Starter

This example displays a simple bar chart of letter counts from a CSV file, with clickable bars that highlight the selected letter and fade the others. Built with React and D3 v7, the React component manages state and dimensions via a `ResizeObserver`, while the D3 code uses `scaleBand` and `scaleLinear` to position bars, `axisBottom` and `axisLeft` for axes with gridlines, and `.join()` for data-driven SVG updates. The chart includes a title and axis labels rendered as SVG text.
