For high-quality math diagrams on a personal website, current state-of-the-art options include TikZ for precise control and complex diagrams, but it has a cumbersome workflow. Alternatives like PyTikZ or exporting TikZ to SVG may simplify the process. Technologies like JSXGraph offer JS-controlled diagrams but with less visual appeal. Emerging solutions potentially include custom JS libraries integrating KaTeX for seamless label rendering and interactivity.
