This example shows a d3.v3 bar chart of letter frequencies in English, loaded from a TSV file, with interactive tooltips that display each bar’s exact frequency on mouseover. The chart uses ordinal and linear scales for positioning, SVG rectangles for bars, and axis components for the x and y scales. Tooltips are added via the d3-tip library, which attaches a styled HTML tooltip to each bar through the `tip.show` and `tip.hide` event handlers, with a custom `html` function formatting the displayed value.

Using d3-tip to add tooltips to a d3 bar chart

This example shows a bar chart of letter frequencies in English, styled with orange bars that shift color on hover. It demonstrates how to add tooltips to a d3 bar chart using the d3-tip plugin, which displays each bar’s exact frequency value on mouseover. The visualization loads data from a tab-separated data.tsv file, renders as SVG with d3.v3, and uses d3.svg.axis for the axes. The tooltip is created with d3.tip, configured with an HTML template, and attached to the chart via svg.call(tip), while mouseover and mouseout events trigger tip.show and tip.hide.

Using d3-tip to add tool

This example shows a bar chart of letter frequencies from a TSV dataset, where hovering over a bar triggers two visual effects: a purple highlight and a custom tooltip displaying the frequency value. The chart uses d3.v3 with SVG rendering and animated transitions. Tooltips are implemented with the d3-tip library, while an additional HTML div tooltip follows the mouse position. The bars animate into place with an elastic easing effect on load, and the axis uses a percentage format.

Using d3-tip to add tool

A bar chart displays letter frequencies from a tab-separated data file, with green bars that turn purple on hover. The d3-tip plugin adds a tooltip showing each letter's exact frequency value when the mouse moves over a bar. Built with d3.v3 and SVG, the chart uses ordinal and linear scales, axis components, and the `.on('mouseover', tip.show)` and `.on('mouseout', tip.hide)` event handlers to trigger the tooltip.

Untitled

This example shows the frequency of each letter in the English language as a bar chart, with orange bars that darken on hover. A tooltip appears on mouseover to display the precise frequency value. Built with D3 v3, it uses ordinal and linear scales, SVG axes, and the d3-tip plugin for tooltips. The data comes from a TSV file and is parsed with a custom type function.

D3: An HTML div tooltip

This example shows a bar chart of 20 numeric values that users can hover over to see a tooltip with the exact data point. The tooltip is an HTML div styled with CSS, and it appears near the cursor using `d3.select` to update its position and text content. The chart uses `d3.scaleBand` and `d3.scaleLinear` for layout, and each rectangle responds to `mouseover` and `mouseout` events to toggle the tooltip’s visibility. Clicking any bar triggers a sorting animation with `transition` and `delay`, reordering the bars by value in ascending or descending order.

d3_tip_plot

This visualization uses a bar chart to show the frequency of a variable over time, with each bar representing a date from February to October 2017. The chart is rendered using SVG via D3.js v3, with an ordinal scale for the x-axis and a linear scale for the y-axis. It incorporates the d3-tip library to display tooltips on mouseover, showing the exact frequency value. Data is loaded from a local CSV file using `d3.csv`, and the bars are colored orange, darkening on hover to highlight interactivity.

D3: An SVG element tooltip

This example shows a bar chart built from a hardcoded array of numbers, with an SVG text tooltip that appears on mouseover to display each bar’s value. The tooltip is appended directly to the SVG and removed on mouseout. Clicking a bar sorts the rectangles in ascending or descending order using a staggered transition. The code uses D3 v4 with `scaleBand`, `scaleLinear`, and `transition` for sorting, while CSS `rect:hover` styling changes the fill to orange.

Reusable D3 Tooltip

This example demonstrates a reusable tooltip function for D3 v4 bar charts, built with SVG. The tooltip, defined in tooltip.js, displays data attributes (name, description) in a styled black rounded rectangle with white text. It tracks mouse position to position itself within a defined extent, flipping sides dynamically based on cursor quadrant. The bar chart itself uses dummy data with categorical x-axis and linear y-axis, and the tooltip is attached to each bar via `.each(tooltip.events)`, preserving any other event listeners. The function is highly configurable through methods like `.tips()`, `.fontSize()`, `.padding()`, and `.margin()`, making it reusable across charts.
