Twenty semi-transparent circles scatter randomly across an SVG canvas, each filled with a distinct color from D3’s `d3.scale.category20` palette. Hovering over any circle triggers a native browser tooltip via an appended SVG `<title>` element, displaying that circle’s specific color name. The example uses D3’s data join to bind randomly generated coordinates and radii, then appends circles and their tooltips. It demonstrates adding interactive title elements directly within D3 selections, with no additional libraries beyond the core `d3.js` script.

MouseOver

This example demonstrates interactive mouse events on an SVG scatterplot built with D3 v3. Circles change color to orange and grow in radius on mouseover, then revert on mouseout. Clicking the background converts pixel coordinates to data values using inverted linear scales, adds a new point to the dataset, and appends a new circle. The code uses `d3.scale.linear`, `d3.svg.axis`, and `.on("mouseover")` handlers to manage the visual feedback and dynamic data updates.

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`.

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.

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.

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.

T3 Tool Tip Template

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.

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.

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.
