This example shows a line chart of stock closing prices over time, with an interactive tooltip that follows the mouse cursor. As the user moves over the chart, a dashed crosshair and a highlighted data point appear, along with text displaying the exact date and closing value. Built with D3.js v5, the visualization uses SVG rendering and relies on `d3.line`, `d3.scaleTime`, `d3.bisector`, and `d3.mouse` to compute and display the nearest data point from the provided CSV data.

AI-generated description

This is a follow on from the simple tooltip graph written with d3.js v5 here.

It extends a tooltip technique which I find particularly neat.

This graph is part of the code samples for the update to the book D3 Tips and Tricks to version 5 of d3.js.

Favorite Tooltip (complex version) v5

This example shows a time-series line chart of stock closing prices with an interactive tooltip that follows the mouse. The visualization uses d3.csv to load the data and d3.line with d3.scaleTime and d3.scaleLinear to render the path, while a bisector and d3.mouse enable precise date lookup. A crosshair and text labels update on mousemove, displaying the exact close value and formatted date near a red circle marker. The SVG also includes dashed guide lines and axes generated with d3.axisBottom and d3.axisLeft.

Favorite tooltip (simple version) v5

This line chart displays a time series of daily closing values from a CSV file, with a tooltip that follows the mouse to reveal the nearest data point. Built with D3 v5 as an SVG visualization, it uses `d3.line`, `d3.scaleTime`, and `d3.scaleLinear` to render axes and the path. A transparent overlay rectangle captures mouse movements, and a `d3.bisector` finds the closest date to position a highlighted circle, which appears on mouseover and hides on mouseout.

Favorite tooltip (complex version)

This interactive line chart displays a time series of stock closing prices, with a crosshair and tooltip that track the mouse to reveal the exact date and value at the nearest data point. The visualization, built with D3.js (version 3.5.17), renders the data from a CSV file as an SVG line chart. It uses D3’s time scale, linear scale, and axes, while the tooltip logic relies on a bisector to find the closest point and updates the position and text of SVG elements on mousemove 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`.

Favorite tooltip (simple version)

This example shows a time-series line chart of stock closing prices, with a tooltip that highlights the nearest data point as the mouse moves across the chart. The chart uses D3.js version 3.5 to parse dates, scale the axes, and draw the line and axes as SVG elements. A hidden circle is repositioned using the `bisectDate` function and the `d3.mouse` coordinates, appearing only during mouseover. The data comes from a CSV file with date and close price columns, rendered with a steel-blue line and grey axes.

Favorite tooltip (simple version) v6

This example demonstrates a line chart of stock closing prices over time, with a tooltip that highlights the data point nearest the mouse cursor. The visualization uses D3 v6 APIs including `d3.scaleTime`, `d3.scaleLinear`, and `d3.line` to render the SVG path, while a bisector function (`d3.bisector`) selects the closest date. A transparent rectangle captures mouse events, and a circle is repositioned via `d3.pointer` and transformations to show the current value. Data comes from a CSV file parsed with `d3.timeParse`.

Favorite tooltip (simple version) v7

This example shows a simple line chart of stock closing prices over time, with a circular marker that tracks the mouse position along the x-axis to highlight the nearest data point. The tooltip itself is minimal—a blue circle that appears on mouseover and moves with the cursor, using a bisector to find the closest date. The visualization is built with D3 v7, using `d3.line`, `d3.scaleTime`, and `d3.scaleLinear` to render an SVG path and axes. Data comes from a CSV file parsed with `d3.csv`.

Favorite tooltip (complex version) v6

This visualization displays a time series line chart of stock closing prices from late March to early May 2012, using SVG rendering with D3.js v6. It shows a sophisticated tooltip that tracks the mouse position along the x-axis, drawing dashed horizontal and vertical guide lines, a circle marker at the nearest data point, and displaying both the date and closing value. The tooltip uses the `d3.bisector` API to find the closest data point, `d3.pointer` for mouse coordinates, and the inverse x-scale to map the pixel position back to a date. The value and date labels are layered with white outlines to improve readability.
