This example demonstrates a reusable tooltip system for data visualizations, where hovering over 50 randomly positioned circles displays their x, y, and id properties in a floating HTML div. The tooltip intelligently flips its position near the window edges using mouse coordinates from the d3.pointer API. The implementation uses D3 v6 selection methods like .on mouse events and .join for dynamic content, while custom CSS styling creates the visual tooltip appearance. The SVG-rendered circles change color from gray to magenta when hovered, with tooltip contents generated from each data object's entries.

OnMouse Events and ToolTips

This example demonstrates interactive SVG circles that respond to mouse events with tooltips. The visualization renders three orange circles of varying sizes on a whitesmoke background, each containing a distinct message. Using D3 v7 with the d3-selection-multi extension for chained attribute calls, the code binds data to circle elements and applies radius, position, and fill properties. The SVG canvas is 1000 by 800 pixels, with tooltip functionality triggered through the message property in the dataset.

T3 Test

A field of 150 colored circles of random size, position, opacity, and color fills the browser window. Hovering over a circle reveals a styled tooltip displaying the circle's data (x, y, and id) in a table. The tooltip repositions to stay within the viewport, and the circle's fill color transitions to a new random color. Built with D3 v7, this demo uses selection-based event handlers (`mouseover`, `mousemove`, `mouseleave`) and D3's `transition` to animate the color change.

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

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.

Tooltip example

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.

Reusable D3 Tooltip

This example demonstrates a reusable tooltip function for D3 v4 bar charts, built with SVG. The tooltip, defined in tooltip.js, displays data attributes (name, description) in a styled black rounded rectangle with white text. It tracks mouse position to position itself within a defined extent, flipping sides dynamically based on cursor quadrant. The bar chart itself uses dummy data with categorical x-axis and linear y-axis, and the tooltip is attached to each bar via `.each(tooltip.events)`, preserving any other event listeners. The function is highly configurable through methods like `.tips()`, `.fontSize()`, `.padding()`, and `.margin()`, making it reusable across charts.

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.
