This example demonstrates animated line drawing in SVG using D3.js. Four data points (x, y coordinates) are plotted as circles colored yellow or blue based on their x-value, with a natural cubic spline curve passing through them. The line initially appears with a dash offset and transitions to full visibility over three seconds using D3's `transition()`, `easeLinear`, and a repeating `on("end")` callback. The `d3.line()` function with `curveNatural` generates the path geometry in a React environment.

Two circles move left to right across an SVG canvas, tracing a sine wave vertically as they travel. A black line connects their current positions, forming a dynamic segment that shifts with each animation frame. The visualization uses D3’s `select`, `range`, and `join` methods to update circle attributes, while `setInterval` drives the animation loop and a custom `drawLine` function appends and removes the connecting line. Randomly generated array manipulation is also present but unused in the final rendering.

This example shows how to connect pairs of points with lines using D3.js version 3 within a React framework, rendering the result as SVG. It defines a dataset of three line segments, each containing two coordinate pairs, and plots them on a Cartesian grid with linear scales for the x and y axes. The code uses `d3.svg.line()` to generate the path data for each segment and applies it to SVG path elements via `.datum()` and the `d` attribute, while axis generation relies on `d3.svg.axis()`.

This example visualizes three separate line segments, each connecting two points on a scatterplot-like coordinate system. The data is defined as an array of coordinate pairs, and D3.js v3 scales map these values to pixel positions. Using `d3.svg.line()` and `d3.svg.axis()`, the code generates SVG paths and axes within a React-rendered HTML page. The rendering approach relies on SVG elements appended to a container, with margins applied via a translation transform.

This example demonstrates how to connect multiple pairs of points with straight lines in a Cartesian coordinate system using D3.js v3. The visualization renders three separate line segments, each defined by two endpoints, on an SVG canvas with labeled x and y axes. The code uses d3.svg.line() to generate the path data, d3.scale.linear() for coordinate mapping, and d3.svg.axis() to draw the axes. Data is stored as an array of coordinate pairs in JavaScript, and each line is appended as an SVG path element with a distinct stroke color.

This example shows a continuously updating line chart that plots random data points in real time, with a smooth curve and a filled area beneath it. The chart scrolls horizontally as new points are added, while the x-axis shifts to keep the latest data in view. It uses D3 v4 scales and generators such as `d3.line` with `d3.curveCardinal` for the smooth path, `d3.area` for the fill, and `d3.axisBottom` for the axis. Animated transitions with `transition.attr` and `ease` shift both the path and area, with grid lines drawn as static SVG paths.

This example visualizes hierarchical data as an animated SVG tree, with nodes positioned by level and linked to their parents via curved line segments. The code uses D3 v6 functions including `d3.line()` with `curveNatural`, `d3.select()`, and `d3.transition()` with `easeLinear` and `stroke-dashoffset` animation to draw connecting paths. The tree structure is defined in a static array of objects with node, value, parent, and level properties, and the layout algorithm computes positions dynamically based on parent coordinates and level depth. Rendering is done entirely through SVG elements appended to the viewport-filling canvas.

This example shows a single orange diagonal line drawn on a blank 960×500 SVG canvas, rendered directly within an HTML page. The line spans from the upper-left to the lower-right area, with a thick 10-pixel stroke and no interactivity or animation. The code uses raw SVG elements—`<line>`, `<g>`, and `<svg>`—with inline CSS attributes for stroke color and width, and is written in plain HTML without any JavaScript or external libraries. The data source is not present; the visualization is purely a static graphical primitive.

This example shows a collection of geometric shapes rendered directly in SVG, including circles of varying radii and colors, a navy line from the origin, and a red path with arc and quadratic curve segments. The code uses plain SVG element syntax within an HTML file, with a commented-out rectangle demonstrating how to toggle shapes. Each shape is positioned explicitly via cx, cy, x, y, and path data attributes, and styling is applied through fill, stroke, and stroke-width properties. The visualization is static, with no interaction or data binding, serving as a bare-bones demonstration of basic SVG drawing primitives in a standalone page.
