webpagestickynotes.com has a diagram menu powered by js-sequence-diagrams, mermaid.js, flowchart.js &amp; d3.js that allows frictionless text-to-SVG diagram rendering paired with a quick snapshot capability.<p>Additionally, draw.io can produce SVGs with embedded serialized draw.io state. Those SVGs can be added in a document or a sticky note and re-imported back to draw.io for later editing.
