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.

This is my first attempt at a reusable function for creating tooltips on D3 charts.

D3: An SVG element tooltip

This example shows a bar chart built from a hardcoded array of numbers, with an SVG text tooltip that appears on mouseover to display each bar’s value. The tooltip is appended directly to the SVG and removed on mouseout. Clicking a bar sorts the rectangles in ascending or descending order using a staggered transition. The code uses D3 v4 with `scaleBand`, `scaleLinear`, and `transition` for sorting, while CSS `rect:hover` styling changes the fill to orange.

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.

D3: An HTML div tooltip

This example shows a bar chart of 20 numeric values that users can hover over to see a tooltip with the exact data point. The tooltip is an HTML div styled with CSS, and it appears near the cursor using `d3.select` to update its position and text content. The chart uses `d3.scaleBand` and `d3.scaleLinear` for layout, and each rectangle responds to `mouseover` and `mouseout` events to toggle the tooltip’s visibility. Clicking any bar triggers a sorting animation with `transition` and `delay`, reordering the bars by value in ascending or descending order.

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.

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.

D3: A browser default tooltip

This example shows a bar chart where hovering over any bar triggers the browser's default tooltip to display the bar's value. Clicking on any bar alternates the sort order of the bars between ascending and descending, with a staggered animation that repositions each rectangle. The chart is built with D3 v4, using `d3.scaleBand` and `d3.scaleLinear` to map the array of twenty numbers to SVG rectangles. The animation relies on the `transition()` method, with `d3.ascending` and `d3.descending` comparators applied to the data on each sort.

Bar Chart

This example shows a simple bar chart with a tooltip displaying each bar’s label and value on hover. The chart is rendered as SVG using D3 v3, with an ordinal x-axis and linear y-axis. Bars are filled from a custom color palette, and a mouseover event triggers a tooltip whose position follows the cursor. The data is hardcoded in the page as an array of label–value pairs.

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.
