A step-before line chart plots randomized x/y data, and a semi-transparent circle tracks the mouse position along the path during hover, using D3’s SVG path `getPointAtLength` and `getTotalLength` to interpolate the nearest point. The chart includes randomized axes, draggable circles, and a click animation that spawns and removes expanding rings. Data is generated with `Math.random()` and rendered with D3 3.5.5, using SVG elements and CSS transitions for visual feedback.

MouseOver

This example demonstrates interactive mouse events on an SVG scatterplot built with D3 v3. Circles change color to orange and grow in radius on mouseover, then revert on mouseout. Clicking the background converts pixel coordinates to data values using inverted linear scales, adds a new point to the dataset, and appends a new circle. The code uses `d3.scale.linear`, `d3.svg.axis`, and `.on("mouseover")` handlers to manage the visual feedback and dynamic data updates.

path

A black vertical rule tracks the mouse horizontally across an empty SVG canvas. The visualization relies on D3 v4 event handling: a transparent rectangle captures mouseover and mousemove events, updating the path element’s `d` attribute to draw a line from the top to the bottom of the plotting area. The mouse-out event fades the line to opacity zero. The code uses `d3.select`, `d3.mouse`, and style manipulation, though no data is displayed—only the interactive guideline.

Mouse Interactions

A black canvas responds to mouse movement by tracking the cursor with a glowing radial-gradient circle and a white text label reading “3v@n.” Simultaneously, an animated white line chart grows from left to right, plotting a random walk that meanders vertically across the screen. The visualization uses D3 v7 to manage SVG elements, with event handlers on `mousemove` and `click` updating the cursor marker, while a `setInterval` drives the chart’s incremental path construction and opacity fade.

rounded-corner-curve

An interactive line chart demonstrates a technique for drawing smooth paths with rounded corners through data points, contrasting it with a standard linear interpolation. The example generates random data and displays two paths: a default black line and a magenta path with rounded corners. Moving the mouse horizontally adjusts the rounding intensity in real time, revealing how the SVG path `C` (cubic Bézier) commands create the effect. The code uses d3.js for data generation and SVG path construction, with custom logic for path string manipulation.

mouseover-moire

This example demonstrates a mouseover-driven moiré pattern, where moving the cursor over the SVG canvas dynamically rotates and rebuilds two layered line grids. The visualization shows how intersecting line families create shifting interference patterns that respond to pointer position. The code uses D3 v3 to append line elements to two separate groups within an SVG, with the mousemove event triggering a function that regenerates both grids and applies a rotation transform based on cursor coordinates. The line count and spacing are controlled by a linear scale, and the grids are drawn from source data derived from the cursor’s vertical position.

Event Handling-- mouseover, mouseout, still has bug

This example demonstrates interactive data points on a scatterplot, where hovering with the mouse highlights a circle by changing its fill to orange, doubling its radius, and displaying its x and y coordinates as a nearby text label; moving the mouse away reverts these changes. Users can also click anywhere on the SVG to add a new circle at that location, appending the coordinates to the dataset. The visualization uses d3.v5 with SVG rendering, employing d3.scaleLinear for axes and d3.axisTop and d3.axisLeft for tick marks. Event handling relies on the `.on('mouseover')` and `.on('mouseout')` methods, though the code contains a typo, `'mouiseout'`, in the click handler, which prevents proper mouseout behavior for newly added points.

Mouse event

An interactive SVG canvas responds to mouse movement and clicks by spawning animated circles and falling letterforms. Moving the cursor triggers a bouncing circle at its position, while clicking or a timer initiates a rain of random characters. The visualization uses D3.js transitions to animate opacity, size, and position, with colors generated procedurally via a golden-ratio hue rotation.

linked-hover

Linked-hover displays two line charts drawn side by side from randomly generated data, each with 100 points. Hovering over a circle in either chart emphasizes the corresponding point in both charts by enlarging it and adding a blue stroke, while also updating the URL hash to reflect the selected index. The visualization uses D3.js v3 for SVG rendering and axes, with lodash helpers for data manipulation. The linked selection is driven by mouseover events and a shared setHover function that applies transitions to all circles, ensuring synchronized highlighting across charts.
