This example demonstrates a basic tooltip interaction: hovering over a green circle reveals a text box that follows the mouse cursor. The tooltip is created as a separate HTML `div` element positioned relative to the page. The code uses `d3.select` to append an SVG circle and the tooltip div, and employs the `.on("mouseover")`, `.mousemove`, and `.mouseout` event handlers with `tooltip.style` to control visibility and position based on `event.pageX` and `event.pageY`. It runs on d3.v7 and renders all visual elements as SVG.

tooltips

This example demonstrates a simple tooltip that appears when the user hovers over a circle in an SVG. The tooltip is a div element created with d3.select that becomes visible on mouseover, follows the cursor using page coordinates on mousemove, and hides on mouseout. The code uses D3 v7 to append an SVG circle with specified stroke, fill, radius, and position attributes, and binds the mouse events directly to that circle. The tooltip’s text is static, and no external data source is used.

Tooltip

A single SVG circle serves as the target for an HTML tooltip built with D3.js v5. The tooltip, styled with absolute positioning and a border, appears on mouseover, follows the cursor via mousemove events, and hides on mouseout. It contains an image and styled text, demonstrating how D3 can manage interactive HTML overlays alongside SVG shapes. The example uses D3's selection and event handling methods on the circle's ID.

Tooltip example

This example demonstrates a simple tooltip implemented as an SVG `<title>` element attached to a circle shape. The circle, with a radius of 200 pixels, is positioned at coordinates (250, 250) inside an SVG canvas of 960 by 500 pixels. The code uses D3 v6’s selection and `append` methods to create the circle and its child `<title>` node, which displays the static text “It Works” on hover. No data source is involved; the visualization relies entirely on D3’s DOM manipulation and SVG rendering.

Simple D3 tooltip

This example demonstrates a minimal tooltip interaction in D3.js, showing how a simple text label appears and follows the mouse cursor when hovering over a circle. The code uses D3 v5 to append a hidden div as the tooltip and positions it dynamically on mouse events. It employs `mouseover`, `mousemove`, and `mouseout` handlers to control visibility and track the pointer coordinates via `event.pageY` and `event.pageX`. The circle is drawn with an SVG `circle` element, styled with a black stroke and aliceblue fill, inside a 300-by-300-pixel SVG container.

Mouseover Example

This example demonstrates a mouseover interaction on a single circle rendered in an SVG. A tooltip appears near the cursor when the circle is hovered, displaying a custom HTML message that includes text and an image, and it disappears when the mouse leaves. The visualization is built with D3.js v6, using `d3.select` to append the SVG and tooltip elements and `.on()` event listeners for `mouseover`, `mousemove`, and `mouseleave` to control tooltip visibility and positioning. The tooltip is styled inline with CSS properties such as `position: absolute` and `visibility: hidden`.

Untitled

This example shows a single green circle that displays a custom HTML tooltip on hover, with the tooltip following the mouse position. The SVG circle and tooltip are created using D3 v4, with the tooltip built as an HTML div styled via inline CSS. Pan-and-zoom functionality is enabled through `d3.zoom`, which applies a transform to the SVG group. Mouse events use `d3.mouse` to position the tooltip relative to the cursor, using `mouseover`, `mousemove`, and `mouseout` handlers.

Tooltip

This example demonstrates a customizable tooltip system built with D3 v4, showing how tooltips can appear in different positions relative to hovered elements. It renders a grid of small aqua squares, and hovering over any square changes its color to orange while displaying a tooltip with contextual information about that specific item, such as its number, whether it is even, and its prime status. The tooltip’s appearance and behavior—including direction, color, content rows, and arrow styling—are configured through a reusable `d3.componentsTooltip` API, with live code editing via CodeMirror. The implementation uses SVG rendering and mouse event handlers to trigger tooltip visibility.

SimpleToolTip

A simple D3.js example demonstrates a basic tooltip for a single SVG circle. The visualization shows a 300-by-300 pixel canvas with one aliceblue circle at its center. Hovering over the circle reveals a text label that follows the mouse cursor, positioning itself near the pointer using the element's `mousemove` event. The tooltip is implemented with a div element whose visibility is toggled by `mouseover` and `mouseout` handlers, and its position updates via `event.pageX` and `event.pageY`. The code uses D3's selection and event-handling APIs to attach these interactions to the circle. This example illustrates the basic pattern for adding interactive hover information to a simple geometric shape.
