This example demonstrates a minimal React and D3 starter template for building SVG visualizations. It shows how to fetch and parse a CSV dataset from a GitHub gist using a custom `useData` hook that leverages `d3.csv`, and renders the results inside a reusable `VizContainer` component. The container abstracts the SVG and group elements while following a standard margin convention; an optional `showMargins` prop displays placeholder rectangles to visualize the plotting area. The code highlights the integration of React’s state management via `useState` and `useEffect` with D3’s data loading and SVG rendering.

AI-generated description

Boilerplate code for a React + D3 visualization with:

  • CDN links for React, ReactDOM, and D3
  • Basic React boilerplate
  • Variables for dimensions and margins
  • useData hook to fetch a CSV URL.
  • VizContainer component that:
    • Abstracts SVG/group container elements
    • Follows the margin convention
    • Show the margins, which can be easily removed by deleting the showMargins={true} prop

React + D3 + useData Viz Starter

This example demonstrates a minimal React + D3 starter template for building SVG visualizations with a reusable margin convention. It fetches Hepatitis C data from a CSV URL using a custom `useData` hook built with `useEffect` and `useState`, loading via D3’s `csv` method. A `VizContainer` component abstracts the SVG and group elements, translating the inner group by the specified margins and conditionally rendering gray rectangles to visualize the chart area. The code relies on CDN-loaded React 16, ReactDOM, and D3 v6, with dimensions hardcoded at 960 by 500 pixels.

D3 + React + useData

This example demonstrates how to build a D3.js visualization within a React application using a custom `useData` hook to load CSV data from a GitHub gist. It shows a set of circles whose count and size are dynamically controlled by input fields. The code combines React's `useRef`, `useState`, `useMemo`, and `useCallback` with D3's `select` API for incremental updates, and uses a `VizContainer` component to structure the SVG with margin conventions.

Fork of React + D3 Viz Starter

This example demonstrates a minimal React and D3.js starter project, fetching a CSV file of CSS color names and their hex codes from a GitHub gist using `d3.csv`. The code sets up a fixed 960×500 SVG canvas with margin conventions and uses a reusable `VizContainer` component to render the SVG and a group element. While the visualization is not fully implemented, the structure includes a commented-out mapping of colors in the data to inline-styled `<div>` elements, and the container can display its margins via a `showMargins` prop. The program currently only outputs “Hello world” after loading the data.

React + D3 Viz Starter

This example presents a minimal React and D3.js starter template for building SVG data visualizations. It defines a reusable `VizContainer` component that manages an SVG canvas with configurable dimensions and margins, following the standard margin convention for chart layouts. The component optionally renders background rectangles to visually indicate the plot area and outer canvas. The code imports React, ReactDOM, and D3 v6 via CDN, and the main `App` function constructs a single `VizContainer` with a fixed 960×500 pixel size and equal 30-pixel margins.

Fork of React + D3 Viz Starter

This example demonstrates a minimal React and D3.js starter template for building SVG visualizations. It shows how to render an SVG canvas with a configurable margin layout and placeholder data structure containing four categorical values. The `VizContainer` component abstracts the SVG and group elements, following a margin convention that can be visually highlighted via a `showMargins` prop. The code uses ReactDOM for rendering, D3 v6 for data handling and selection, and references the ResponsiveWaffleHtml component from the @nivo/waffle library, though the actual chart is not rendered in the visible boilerplate output.

React + D3 Viz Starter

This example presents a blank React + D3 starter template that establishes the foundational structure for a visualization. It uses CDN-loaded React 16.13.1, ReactDOM, and D3 v6.2.0 to render an SVG via the `VizContainer` component, which applies the margin convention and abstracts the outer and inner rectangle elements. The code defines explicit width, height, and margin variables, and the component conditionally displays the margins based on a `showMargins` prop. The rendered output is an empty SVG with grey and light-grey rectangles, ready for chart content.

Fork of React + D3 Viz Starter

This visualization gallery example presents a blank React application built with D3, using CDN links for React, ReactDOM, and D3. The code defines a `VizContainer` component that abstracts SVG and group elements, following the standard margin convention. It renders a 960 by 500 pixel SVG canvas with inner and outer rectangles that visualize the plotting area boundaries. The boilerplate sets up variables for dimensions and margins, with the `showMargins` prop toggleable to display or hide these reference rectangles. No actual data or chart is rendered, only the container structure.

Fork of React + D3 Viz Starter

This example demonstrates a React + D3 visualization starter template, displaying a blank SVG canvas with gray and light-gray rectangles that highlight the margin convention. The code loads remote JSON data via `d3.json` but does not yet render it, focusing instead on the boilerplate structure. A `VizContainer` component abstracts the SVG and group elements, using the margin convention to position inner content. The visualization relies on React 16 and D3 v6 loaded via CDN, with SVG rendering for the output.
