This example shows a simple interactive counter where a button click increments a numeric display. It demonstrates how to build a reactive UI using D3's selection and data join methods, with the `setState` function managing state updates. The code uses D3 v7, specifically `select`, `selectAll`, `join`, and `.on` event listeners, while styling the button and counter with flexbox in CSS. The counter text updates dynamically to reflect the current count, and the example highlights D3's role in handling both DOM manipulation and state-driven rendering.

An implementation of a counter based on the VizHub V3 hot reloading patterns. This example demonstrates how to use the index.js pattern with standard UI elements like buttons and divs using D3.

Common UI Elements with D3

This example demonstrates how to build a simple interactive counter using standard UI elements with D3. It shows a button and a text display that updates the click count in real time. The implementation uses D3 selections to create the button and counter div, with event handling via the `on` method to update application state. The `state` object manages the count, and `setState` triggers re-rendering. The code leverages D3's data join pattern with `selectAll` and `join` to bind elements. Styling is handled through CSS classes defined in `styles.css`, using Flexbox for centered layout and green button styling.

Counter

A counter app shows a large numeric count that increases or decreases via two buttons, styled with large typography and a simple layout. It demonstrates the d3-component library for defining reusable components like `countDisplay`, `buttonPanel`, and `button`, while managing state with Redux. The top-level `app` component composes these pieces, and renders update on store subscriptions. The example bridges D3 v4's component pattern with Redux's reducer and dispatch flow.

Simple Unidirectional Data Flow

This example demonstrates a simple unidirectional data flow pattern, using a counter that increments on button click. The current count is displayed in the DOM, and each click dispatches an INCREMENT action to a reducer function, which returns a new state object. The updated state is then passed to a render function that updates the text content of the counter element. The code uses vanilla JavaScript, with plain DOM methods like `getElementById` and `addEventListener` to handle interaction and rendering.

ReactSimple

This example demonstrates a simple interactive web app using React to track click counts on a page. It shows two buttons and a text block that display the number of times they have been clicked, with the app state managed through React’s `useState` and event handlers like `onClick` and `onContextMenu`. The code uses React 16.9 and ReactDOM to render SVG elements, and it includes a reference to a D3-loaded CSV dataset from a GitHub gist, though the dataset is not visualized in the current interaction.

React State Hook example

This example demonstrates a minimal React component that uses the `useState` hook from React 17 to track and display a numeric click counter. It renders a button and a paragraph showing how many times the button has been clicked, with each click updating the state and re-rendering the component. Built with ReactDOM rendering into a root div, the visualization uses `d3.v7` for potential data manipulation but does not directly call any d3 functions. The code shows a simple state-driven interaction rather than a graphical chart.

Loading and Parsing CSV data

This example demonstrates a simple React application that counts button clicks, displaying the current total in a paragraph. It shows how D3.js and React can be combined in a single HTML page, with the D3 library loaded via a CDN link. The code uses React’s `useState` hook to manage the count value, and the `ReactDOM.render` method to mount the app into the DOM. The interface increments the displayed number each time the user clicks the button, illustrating basic state management in a web visualization context.

On click increment[count and setcount]

This example demonstrates a simple counter interface with a button and a display. Clicking the button increments a numeric count value shown in a large paragraph element, with the current total displayed in the text "click the button {count}". The implementation uses React's `useState` hook to manage the count state and `setcount` to update it, while the `onClick` event handler triggers the increment function. The interface is rendered via ReactDOM's `render` method into a root div, with styling applied through embedded CSS that enlarges the text and button for visual emphasis.

useState

A React counter demonstrates the `useState` hook for managing numeric state, with buttons that increment and decrement a displayed number. The code uses functional updates to avoid stale closures and shows how initial state can be provided either directly or lazily via a function, logging console messages to illustrate when each initialization runs. Rendering uses `ReactDOM.render` into a root div, with the interface styled by large CSS font sizes.
