A number input field controls the rotation angle of a text element in an SVG scene. The example demonstrates a simple interactive data-binding pattern: a labeled HTML `<input type="number">` with min, max, and step constraints updates the `rotate` transform of a `<text>` element via d3.js v4's `d3.select(...).on("input")` event listener. The text "d3noob.org" is positioned at the center of a fixed 600×300 SVG canvas, and every input change recalculates its angle from 0 to 360 degrees. The source is a gist by d3noob, rendered entirely with SVG.

AI-generated description

This is a demonstration of the use of the html 'number' input to rotate a text element using d3.js v4.

This graph is part of the code samples for the update to the book D3 Tips and Tricks to version 4 of d3.js.

This example demonstrates how an HTML number input controls the rotation of an SVG text element. It shows a text label displaying the current angle value, with a numeric input field that adjusts the text’s rotation from 0 to 360 degrees in 5-degree increments. The visualization uses d3.v7 to select the input and update the text’s `transform` attribute dynamically through an `input` event listener. The SVG is rendered directly in the browser, with the text element positioned at a fixed coordinate and rotated based on the user’s input.

Input (number) test

This example demonstrates how an HTML numeric input controls the rotation of an SVG text element. A `<input type="number">` tag, initialized at 0 with a range of 0–360 and step increments of 5, triggers the D3.js `on("input")` event to update the text’s `rotate` transformation. The rotation angle is displayed in a span beside the input. Rendered as inline SVG using D3 v3.5.17, the text "d3noob.org" is positioned via `translate(300,150)` and dynamically rotated based on user input. The update function recalculates the `attr("transform")` value on each change.

This example demonstrates how an HTML number input controls the rotation of a text element in an SVG. A label displays the current angle value, while a d3-selected input fires an update function on each change. The code uses d3.v5 to select the input, append an SVG, and apply dynamic transform attributes with `rotate()`. The text element, initialized at zero degrees, rotates from 0 to 360 degrees in 5-degree steps as the user adjusts the input.

This example shows how an HTML number input can control the rotation of a text element in an SVG graphic. The page displays a text label reading "d3noob.org" centered at coordinates (300, 150) within a 600x300 SVG canvas. The code uses `d3.select` to bind an `input` event listener to the number field, and the linked `update` function reassigns the SVG `transform` attribute with the specified rotation angle. The value displayed in the label is updated via a `<span>` element, demonstrating dynamic interaction between form elements and D3-rendered visuals.

A slider input controls the rotation angle of a text element in an SVG graphic. The example demonstrates how an HTML range input can drive D3.js v7 updates, showing the text "d3noob.org" rotating from 0 to 360 degrees. The code uses d3.select to bind the input event, updating both the displayed angle value and the text's transform attribute. The SVG is rendered with D3's selection and append methods within a static 600x300 canvas.

A simple HTML range input controls the rotation of a text label in an SVG element, with the current angle displayed live beside the slider. The example uses D3.js version 3.5.17 to select the input element and bind its `input` event, updating both the text label and the `transform` attribute of the SVG `<text>` node via `attr`. The SVG is appended to the body with a fixed width and height, and the text is centered at coordinates (300,150). The code demonstrates event-driven interaction between native HTML form controls and D3-managed SVG rendering.

This example demonstrates how an HTML range slider can control the rotation of a text element rendered as SVG. The display shows the text “d3noob.org” centered on a 600 by 300 canvas, with its angle dynamically updated as the slider moves. Built with d3.js v4, the code uses d3.select to bind input events, update the displayed angle value, and apply rotation via the transform attribute’s rotate() function. The initial state is set to zero degrees, and the slider’s range spans from 0 to 360 degrees.

A single-page D3.js v5 visualization demonstrates how an HTML range input controls the rotation of two text elements. The page displays "d3.js" and "d3noob.org" as SVG text, and a slider labeled "angle" adjusts the transform attribute of both labels. Moving the slider rotates the first label clockwise from 0 to 360 degrees while the second rotates counterclockwise in the opposite direction, with the current angle displayed live. The code uses D3's selection API, including `d3.select` and `.attr("transform", ...)`, to update the SVG elements in response to the input's `on` event handler.
