A simple line chart plots stock closing prices over time using a dataset from a CSV file. The visualization adds interactive tooltips that appear on mouseover for each data point, displaying the formatted date and closing value. Built with d3.js v5, the chart uses `d3.csv`, `d3.timeParse`, `d3.scaleTime`, `d3.line`, and `d3.axisBottom`/`d3.axisLeft`. SVG circles are overlaid on the line, and a tooltip div animates opacity on hover using the `d3.event` coordinates for positioning.

AI-generated description

This is a simple graph demonstrating the addition of tooltips with a graph. This was written using d3.js v5 and is a follow on to the simple scatter plot example here.

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

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.

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.

Simple tooltips in v6

This example shows a line chart of stock closing prices over time, with circular data points that reveal a tooltip on mouseover. The tooltip displays the formatted date and closing value. 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`.

Tooltip with link in v5

A line chart shows stock closing prices over time, with each data point rendered as a circle. Hovering over a circle triggers a tooltip containing the formatted date and price, where the date is wrapped in a hyperlink. The visualization uses D3 v5 with `d3.csv` for data loading, `d3.scaleTime` and `d3.scaleLinear` for axes, and `d3.line` for the path. The tooltip is a div updated via mouseover events and animated with a CSS transition.

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.

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 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.

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.
