rotating pendulum
✓ Published0🌍 Public
A single black dot orbits an invisible elliptical path around the center of the screen, with two black lines drawn from the top and bottom edges to the dot’s current position. The animation updates every 100 milliseconds using a setInterval loop, incrementing a time variable that drives the dot’s coordinates via trigonometric functions. Built with React and D3.js, the visualization uses D3 selections and `.join()` to create and update SVG `circle` and `line` elements, with the ellipse drawn as an empty SVG `ellipse` shape.
