This example shows a dropdown menu with six pet options—dog, cat, hamster, parrot, spider, and goldfish—where changing the selection updates the application state, though no visible output reflects the current choice. The visualization is built with D3 v7, using a unidirectional data flow where a `viz` function renders the menu and a `setState` callback updates the state and triggers re-rendering. The `menu` module uses D3’s `.join()` to create the `select` and `option` elements, binding the change event to `onChange`, while the `index.js` orchestrates the state management and rendering cycle.

A dropdown menu lets the user choose one of six pets: dog, cat, hamster, parrot, spider, or goldfish. The menu is built with D3’s data join, binding each option’s value and label to an HTML `<select>` element. The selected value is stored in a state object and passed to the `menu` function, which uses D3’s `.on('change')` to update the state and re-render the visualization. The example demonstrates a reusable menu component pattern with `select` and `join`, driven by a simple state management loop.

This visualization demonstrates a simple pet-selection menu built with D3 v7. It uses a drop-down select element to choose from six animal options, with the current value managed through a state object and `setState` function. The menu implementation uses D3's `selectAll` and `join` APIs to efficiently update the DOM, while the `viz.js` module initializes the default selection to 'hamster' and renders the interface.

Menu Options in D3

This example shows a dropdown menu for selecting a pet, with options ranging from Dog to Duck. The visualization uses D3 v7 to render the menu, managing state through a custom `setState` function that tracks the currently selected value. When a user changes the selection, the `menu` function updates the option elements using D3’s data join, and the selected value is logged to the console. The menu’s appearance is styled with CSS, centering it on the page.

Fork of Menu

This example displays a simple dropdown menu for selecting a pet, with the current choice reflected in the menu’s value. The visualization uses D3 v7’s `select` and data joins to bind an array of option objects to `<select>` and `<option>` elements. State management is handled through a custom `setState` function that updates the selected value and triggers a re-render of the menu. The code demonstrates how to build and update an interactive form control using D3’s declarative data-binding approach.

A dropdown menu lets users choose among dog, cat, or fish. The menu is built with d3.select, joining option elements to an HTML select element and binding each option’s value and label from a static array. The change event logs the selected option’s data to the console, demonstrating a minimal d3-based form control without any linked visualization.

Dataviz 9 - Menus

This example demonstrates a simple pet-selection interface built with React. A dropdown menu lets users choose from a list of six animals, including dog, cat, hamster, parrot, spider, and goldfish, with the selected value logged to the console. The code uses React’s `useState` hook to manage the current selection and renders a custom `Dropdown` component, which wraps a native HTML `<select>` element. The `Dropdown` receives options, an ID, and a change handler, updating the state whenever the user picks a new value.

Menu with React

A dropdown menu built with React offers a selection of pet options (dog, cat, hamster, parrot, spider, goldfish), and the chosen value is logged to the console. The page renders an HTML `<select>` element via React’s `useState` and event handling, styled with a large font. D3.js is loaded but unused; the visualization is purely an interactive form component rendered through ReactDOM.

dv.30 - menus w/ react

A pet-selection interface shows a dropdown menu listing six animals—dog, cat, hamster, parrot, spider, and goldfish—with the parrot preselected. A React state variable stores the current choice, and selecting a new value logs it to the console. The custom `Dropdown` component uses React’s `useState`, `onChange`, and `defaultValue` attributes, while D3 v5 and ReactDOM 16.9 are loaded via unpkg, with the menu styled through global CSS.
