This example demonstrates an interactive bar chart with a hover tooltip. It shows a dataset of 20 numeric values represented as vertical bars, where hovering over a bar reveals its value in an HTML tooltip that follows the cursor. Clicking a bar triggers a sorting animation, alternating between ascending and descending order. The visualization uses D3.js v4.5.0 with `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and SVG rect elements. The tooltip is positioned absolutely and updated on mouseover events.

90. D3 Browser Tooltip Text

A bar chart displays a dataset of 20 values as clickable, blue-tinted rectangles. Clicking a bar sorts the bars in either ascending or descending order, with a staggered transition that animates each bar to its new position over one second. The chart is rendered with SVG and uses D3 v4.5.0, specifically `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.ascending`/`d3.descending` for sorting. A native browser tooltip appears on hover, showing each bar's value via an appended `title` element. The bars also change color to orange on mouseover.

91. D3 SVG Tooltip

A bar chart of twenty values rendered as SVG rectangles uses D3.js version 4.5.0 to display a dynamic tooltip on mouseover. The tooltip is created by appending a text element to the SVG at the bar’s position, showing the data value, and removed on mouseout. Clicking a bar triggers a sorting animation using `transition().delay()` and `duration()` to reorder bars by value. Bars also change color to orange on hover via CSS.

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.

89. D3 Browser Tooltip

A collection of vertical bars displays a static dataset, with a default browser tooltip appearing on hover. The bars, colored with a blue scale based on their value, are rendered as SVG rectangles using a band scale for positioning and a linear scale for height. Clicking a bar triggers an animated sort that reorders the bars in either ascending or descending order, with each bar transitioning to its new x position with a staggered delay. The example uses d3.scaleBand, d3.scaleLinear, and transition.attr to implement the sorting behavior.

82. D3 Mouseover

A static bar chart displays a dataset of 20 numeric values as vertical bars with blue fills and white value labels. Using the D3.js v4 library, the example demonstrates a basic mouseover interaction: hovering over any rectangle changes its fill color to orange. The visualization is built with SVG elements generated through `d3.scaleBand` for x-axis positioning, `d3.scaleLinear` for y-axis scaling, and event listeners attached via the `.on("mouseover", ...)` method. The code creates the SVG container, binds data to rectangle and text elements, and applies the color change directly to the selected node.

81. D3 Hover

A simple bar chart displays twenty numeric values as vertical bars, with each bar labeled by its value and colored in a blue gradient. The example demonstrates a CSS-only hover effect, where hovering over any rectangle turns it orange. Built with D3.js version 4.5.0, the code uses `d3.scaleBand` to position bars along the x-axis, `d3.scaleLinear` for the y-axis, and SVG `rect` and `text` elements for rendering, with hover styling defined via CSS `:hover` selector.

86. D3 Sort Hover

A bar chart displays 20 rectangular bars of varying heights, rendered in SVG with a blue gradient based on value, and white numeric labels above each bar. Clicking any bar triggers a transition that sorts all bars in ascending order by value over one second using `d3.ascending` and the `transition` API with `duration` and `attr` for repositioning. Hovering over a bar changes its fill to orange via CSS. The chart uses `d3.scaleBand` for x positioning and `d3.scaleLinear` for y scaling, with the dataset hardcoded in the code.

D3: A browser default tooltip

This example shows a bar chart where hovering over any bar triggers the browser's default tooltip to display the bar's value. Clicking on any bar alternates the sort order of the bars between ascending and descending, with a staggered animation that repositions each rectangle. The chart is built with D3 v4, using `d3.scaleBand` and `d3.scaleLinear` to map the array of twenty numbers to SVG rectangles. The animation relies on the `transition()` method, with `d3.ascending` and `d3.descending` comparators applied to the data on each sort.
