This example shows how to read the currently selected value from a group of radio buttons using D3.js. It displays three gender options—Male, Female, and Other—with the Male option preselected, and logs the selected value to the browser console. The code uses `d3.select('input[name="gender"]:checked').property("value")` to retrieve the initial selection, and `d3.selectAll('input[type="radio"]').on("change", ...)` to listen for user changes, printing each newly selected value via the `this.value` property. The data is embedded directly in the HTML form elements.

Input

This example demonstrates two groups of radio buttons for selecting options, with a form that captures and displays the chosen contact method as text output. The page combines static HTML form elements with a JavaScript event listener that uses the FormData API to log submitted values. Styling relies on CSS with monospace fonts, rem-based spacing, and a highlighted class for visual emphasis. The code uses standard browser APIs—including addEventListener, preventDefault, and querySelector—to handle form submission without any external visualization libraries.

D3 Radio buttons

This example shows a scatterplot of 200 randomly generated points, with radio buttons that filter points by their x-value. Selecting a threshold highlights points above that value in red while leaving the rest black. The code uses D3 v7 to create the SVG, scales, and axes, and attaches click handlers to the radio inputs. The transition method animates the fill color change over 500 milliseconds.

React Radio Buttons

This example demonstrates a simple React user interface where two radio buttons, labeled Size and Count, toggle a selection. The interface uses React’s `useState` hook to track the currently chosen value, which is logged to the console on change. The `Radio` component receives an `onSelectedValueChange` callback prop, invoked with the selected `event.target.value` upon input change. Built with React 16.13.1 and rendered via `ReactDOM`, it showcases controlled component state management without any external data or visualization libraries.

html: form radiobutton

This example demonstrates a minimal HTML form control for a radio button, showing a single selectable option with an associated label. The code uses native HTML markup with the `input` element set to `type="radio"` and a `name` attribute of `"set-radio"`, paired with a `label` element using the `for` attribute to link it to the input’s `id`. The rendering relies entirely on the browser’s default styling for form elements, with no external libraries or custom JavaScript. The interaction is limited to toggling the radio button’s checked state, as defined by the HTML specification. No data source or advanced visualization API is involved; the example focuses solely on the structural and semantic foundation of a radio-button input.

Chart Controls I

This example demonstrates an interactive multi-series line chart where users can toggle the visibility of data for Europe, Asia, and America using radio buttons. The chart renders three time-series lines from a TSV file, with each line colored via a categorical scale. The code uses D3 v3’s `d3.svg.line`, `d3.time.scale`, and `d3.svg.axis` for scaling and axes. Radio button changes apply a CSS class to hide or show entire paths within the SVG group.

Menus React

The example shows a React component that renders a dropdown menu with three predefined options (Valor1, Valor2, Valor3), where the current selection is tracked in React state via the `useState` hook. It demonstrates how a controlled `select` element updates its displayed value and logs the selected value to the console. The `Dropdown` component receives options, an ID, a selected value, and a callback, using React 17 and D3 v6 loaded via CDN. The menu is styled with large font sizes for labels and selects, and the root element is rendered using `ReactDOM.render`.

Group Select

This interactive visualization demonstrates four different approaches to grouping elements within a network graph, using a dataset of events with attributes like eventName, index, and traceId. Users toggle between group types via radio buttons, which triggers D3.js functions to rebuild the visualization and display a text label for the selected grouping. The code leverages D3 v4 and the WebCola layout library (accessed as `cola.min.js`) to manage the graph structure, while the interaction relies on D3’s `json()` method to load the graph data and event handlers to respond to user input. The current implementation primarily updates text labels and a dropdown menu, with the actual graph rendering handled by the underlying libraries.

Bind data to html with d3

This example demonstrates how to bind external JSON data to SVG elements using D3. The code loads eye color and gender data from a GitHub gist, filters and transforms the entries into valid hexadecimal colors, then sorts them by blue channel value. It binds the data to circles, positioning them horizontally based on their index and coloring each fill with the corresponding eye color. The example uses `d3.json` for data loading, `d3.select` for DOM selection, and the data join pattern with `enter()` and `append()` to create circles without using any scales.
