This example shows a line chart of stock closing prices that, when hovering over a point, displays a tooltip containing the date, the price, and a hyperlink to a related resource stored in the CSV data. The tooltip appears with a fade-in effect and includes an HTML anchor tag that opens the link in a new tab. Built with D3 v3, the code uses `d3.csv` to load the data, `d3.time.scale` and `d3.svg.line` for the chart, and SVG circles with mouseover events to trigger the tooltip, which is a styled `div` positioned at the cursor.

AI-generated description

This is designed to demonstrate generating tool tips with an HTML linkwith links contained in the source csv file. The graph is based on a simple line graph per the book D3 Tips and Tricks and was generated in response to a question on the d3noob.org blog.

It is also a follow on from a slightly simpler version here.

d3.js tool tip with HTML link

This example shows a line graph of date-stock price pairs from a CSV file, where each data point is marked by a circle. Hovering over a circle triggers an HTML tooltip containing a hyperlink to Google, a formatted date, and the closing price. It uses d3.v3 APIs like `d3.time.scale`, `d3.svg.line`, and `d3.select` to build the SVG chart and manage the tooltip’s position and opacity transitions. The tooltip remains active because the `pointer-events` CSS property is not disabled.

Simple d3.js tooltips

A line chart plots stock closing prices over time, with a tooltip that reveals the exact date and price when hovering over a data point. The visualization uses d3.js to render SVG circles for each data point and a path for the line, reading time-series data from a CSV file. The tooltip is implemented using an HTML div that appears via d3 transitions on mouseover and mouseout events, positioning itself near the cursor using `d3.event.pageX` and `d3.event.pageY`. The chart axes employ `d3.svg.axis` with time and linear scales.

Multi-links in tooltips using v4

This example shows a line chart of stock closing prices over time, where each data point is a circle that reveals a tooltip on mouseover. The tooltip displays the formatted date and price, and the date itself is wrapped in a hyperlink that points to a different URL from the CSV data. The visualization is built with D3 v4, using SVG for rendering and transitions for tooltip opacity. Data is loaded from a CSV file with `d3.csv`, dates are parsed with `d3.timeParse`, and the axes are generated with `d3.axisBottom` and `d3.axisLeft`.

Multi-links in tooltips using v5

This example shows a line chart of stock closing prices over time, where each data point is a circle with a tooltip. Hovering over a circle reveals a hyperlink to a related d3.js example, along with the formatted date and price. The visualization uses d3.v5’s `d3.csv`, `d3.timeParse`, `d3.scaleTime`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft`. Circles are drawn with SVG, and tooltips are HTML divs that appear on `mouseover`, linking out to external URLs stored in the CSV data.

The tooltip, styled with CSS, is rendered via `div.html` and includes an anchor tag linking to an external site, with its position set using `d3.event.pageX` and `d3.event.pageY`. SVG circles mark each data point.

Simple tooltips in v4

This example shows a simple line chart of stock closing prices over time, with interactive tooltips that appear when the user hovers over each data point. The tooltip displays the formatted date and closing value near the cursor. Built with d3.js v4, it uses `d3.timeParse` and `d3.scaleTime` for the date axis, `d3.line` to draw the path, and mouseover/mouseout events to animate the tooltip's opacity via `transition`. Data comes from a CSV file and is rendered as SVG circles and axes.
