A line chart displays stock closing prices over time, with circular markers for each data point. Hovering over a marker reveals a tooltip containing the formatted date and closing value, with the date rendered as a hyperlink to an external site. The visualization uses d3.csv to load the timestamped data, d3.scaleTime and d3.scaleLinear for axes, and d3.line to draw the path. Tooltips are implemented as HTML divs positioned via event.pageX and pageY, with opacity transitions on mouseover.

Multi-links in tooltips using v7

A line chart displays stock closing prices over time, with a small tooltip appearing on mouseover for each data point. The tooltip is a persistent, styled `<div>` that shows the date and price, and includes a hyperlink to a related resource. The chart is rendered with SVG using D3 v7, drawing a path for the data series and circles for individual points. The code uses d3.csv, d3.scaleTime, d3.scaleLinear, d3.axisBottom, and d3.axisLeft, with data sourced from data-link.csv.

Tooltip with link in v6

A line chart displays stock close prices over time, with each data point marked by a circle. Hovering over a circle reveals a tooltip showing the formatted date and value, where the date is a hyperlink to Google. The visualization is built with D3 v6, using `d3.csv` to load the data, `d3.timeParse` and `d3.timeFormat` for date handling, and `d3.line` to generate the SVG path. Tooltips are HTML divs positioned via mouse events and animated with opacity transitions.

Simple tooltips in v7

This example shows a line chart of stock closing prices over time, with circular markers at each data point. Hovering over a marker fades in a tooltip displaying the formatted date and closing value. The chart is rendered as an SVG using D3 v7, with `d3.line` for the path, `d3.scaleTime` and `d3.scaleLinear` for axes, and `d3.axisBottom`/`d3.axisLeft` for ticks. Tooltip interactions use mouseover and mouseout events with `transition` to animate opacity. Data comes from a CSV file.

Tooltip with link in v6

This example shows a time-series line chart of stock close prices, with persistent tooltips that appear on mouseover and include a hyperlink to Google. The tooltip displays the formatted date and closing value, anchored to the cursor position. It uses d3.csv to load the data, d3.scaleTime and d3.scaleLinear for axes, d3.line for the path, and d3.axisBottom/axisLeft for rendering. Circles are appended per data point, with tooltip behavior triggered by mouseover events.

Favorite tooltip (complex version) v7

A line chart displays stock closing prices over time, with a crosshair and tooltip that follow the mouse cursor. The visualization uses D3 v7 to render an SVG chart, reading CSV data with `d3.csv` and parsing dates via `d3.timeParse`. A `d3.bisector` finds the nearest data point, while `d3.pointer` locates the cursor position. The tooltip shows the exact date and value, with dashed guide lines and a highlighted circle, using `d3.scaleTime`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft`.

Built with d3.v6, the visualization uses `d3.timeParse` to parse dates, a `d3.line` for the path, and a floating `div` for the tooltip, animated via `transition().duration()`. Data comes from a CSV file, rendered as SVG with axes generated by `d3.axisBottom` and `d3.axisLeft`.
