10 - Simple d3.js tooltip

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 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.

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 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`.

d3.js tool tips with links in data

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.

Simple tooltips in v5

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.
