This example draws an irregular octagon on an SVG canvas and places a rotated blue rectangle at the midpoint of each of its eight edges. The rotation angle of each rectangle is calculated from the slope of its corresponding edge using the arctangent function, so the rectangles align perpendicular to the polygon’s sides. The polygon is outlined in red, and the visualization is built with D3 v6, using SVG elements such as `polygon` and `rect` with a `transform` attribute for rotation. A background image loaded from GitHub serves as the canvas backdrop.

不规则八边形边上绘制柱形图

This example draws an irregular octagon on an SVG canvas over a background image, then places a blue rotated rectangle at the midpoint of each edge to represent a bar chart. The rectangle’s rotation angle is computed from the edge’s slope using `Math.atan2`, and each rectangle is positioned via the `transform` attribute with `rotate`. The code uses D3 v6 to append SVG elements, including a polygon for the octagon and rects for the bars, with hardcoded vertex coordinates and a fixed rectangle width and height.

在八边形边上绘制柱形图

This example renders a red octagon centered in an SVG canvas and draws individual bar charts along each of its eight edges. The bars are positioned at the midpoint of every polygon side and rotated to align with the edge’s orientation. Using D3 v6, the code computes the octagon’s vertices with a custom polygonPoints function, derives side midpoints, and appends SVG rect elements for each bar. It also demonstrates stacked bars via d3.stack(), though the primary visible output uses a fixed array of heights. The bars are styled with red fills and rotated around their base points.

Octagon

This example renders a single, intricate octagonal shape as an SVG path element. The path’s `d` attribute contains a compact sequence of absolute and relative commands (M, H, C, V, Z, L, c, v, h, z, m), building a geometric form with layered curves and straight segments. The design exploits the SVG coordinate system and viewBox to define the shape’s proportions. The code uses no JavaScript or external visualization libraries, relying entirely on static SVG markup and inline path data to produce the final graphic.

Rotation testing

This example tests how SVG rotation transforms reposition geometric shapes. It draws outlined reference squares at different coordinates, then overlays filled squares that have been rotated using both static SVG transform attributes and dynamic JavaScript calculations. The D3.js v6 code uses `select` and `append` to create rectangles, while a custom `rotate` function computes rotated coordinates for one placement. The SVG also includes a complex path of a suitcase, demonstrating how rotation interacts with detailed vector graphics. The visual compares rotation behavior across three test cases, showing direct rotation, rotation with translation, and rotation around a custom origin point.

hex-circle

The visualization shows six identical steelblue circles arranged symmetrically around the center of a square SVG canvas, each rotated 60 degrees apart from its neighbor. The code uses D3 v3 to append a group element for each of the six points, applying a rotation transform based on the index and a fixed translation of 100 pixels outward. Each group then contains a single circle with a radius of 10 pixels. The rendering relies on SVG’s `rotate` and `translate` transforms to position the circles in a hexagonal pattern, with no data beyond the integer range 0–5.

Circular Geometric Patterns

This example renders a geometric pattern of eight circles arranged in a circular layout, with a blue polyline connecting their centers. Using React and D3 v5, the code computes circle positions from trigonometric functions, sizes each circle by the segment length between adjacent points, and draws the connecting path via `d3.line` with `curveLinearClosed`. The static SVG visualization is centered on a 960×960 canvas, with circles stroked in light gray and the polyline highlighted in blue.

SVG Fundamentals

This example showcases a generative composition of triangular polygons arranged on a 960x500 SVG canvas. The visualization demonstrates fundamental SVG shapes and CSS styling, where each polygon is explicitly defined with coordinate points and filled with a gradient of teal colors. The code utilizes native HTML, CSS, and JavaScript, with CSS transitions and hover effects that adjust polygon opacity. The design creates a geometric abstract mosaic, emphasizing how SVG elements can be structured and styled directly within a browser environment without external libraries.

Triangle Pentagon

This example displays a closed polygonal line connecting eight points in a two-dimensional coordinate space, forming a shape reminiscent of a star or a triangle-pentagon hybrid. The visualization uses the D3.js v4 library’s `d3.line()` path generator to convert the array of x-y coordinates into an SVG `path` element, which is then rendered with a blue stroke and no fill. The code appends the SVG container to the document body via `d3.select()`, hardcoding the 1000x1000 pixel canvas and the data points. The geometric pattern is drawn as a single continuous path, illustrating how D3’s line interpolation handles multiple segments within one dataset.
