This example shows a line chart of daily closing prices, displaying a crosshair and a tooltip with the precise dollar value as the mouse moves over the plot. The visualization is built with D3 v4, using the `d3.line` generator to create the path and `d3.axisBottom` and `d3.axisLeft` for the axes. A transparent `rect` overlay captures mouse events, and a `d3.bisector` function finds the nearest data point to the cursor’s x-coordinate, triggering the droplines and value label. The data is loaded from a TSV file with a date and close price per row.

X-Value Mouseover

A line chart of daily closing prices displays a tooltip on mouseover, revealing the exact price at the nearest data point. The visualization uses D3.js v3 with SVG rendering, reading data from an external TSV file. As the mouse moves over an overlay rectangle, d3.mouse and a time scale’s invert method convert screen coordinates to dates, while a d3.bisector identifies the closest entry. The focus circle and text update accordingly, showing the formatted currency value.

X-Value Mouseover

A line chart plots daily closing prices over time. Users hover over the chart to display a tooltip showing the exact monetary value for the nearest data point. The visualization uses D3.js version 3, with a time-scaled x-axis and a linear y-axis. The code employs `d3.mouse` and `scale.invert` to translate the mouse position into an x-value, and `d3.bisector` to locate the closest date in the provided TSV data.

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.

Tooltip with link in v4

This example shows a line chart of stock closing prices over time, with interactive data points that reveal a tooltip containing a hyperlink on hover. Built with d3.js v4, the visualization uses `d3.csv` to load the data, `d3.scaleTime` and `d3.scaleLinear` for axes, and `d3.line` for the path. 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.

Favorite tooltip (complex version) v5

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.

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`.

D3 interactive line chart 2

This interactive line chart displays time-series data points as circles connected by a line, with a large value label for the most recent entry. Hovering over a circle turns it red, reveals a tooltip with the exact value, and draws a dashed vertical guide line down to the x-axis. Built with D3 v4, the visualization uses `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.line` for the path, and animated `transition` calls on mouseover and mouseout events. The x-axis labels are rendered as text elements, and the data is loaded via `d3.json`.

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.
