Hotspot image

A picture with pins that open a note.

Numbered pins sit on a picture drawn in code; each opens a note below it, so the layout never jumps. Arrow keys move from pin to pin and Escape closes the note. The pins and their notes come from props.

Try it

<hotspot-image>

Build one with your agent

Paste this into your agent. It asks you before it signs in, pays or goes further than checking and publishing.

Build me a Taggor component like "Hotspot image" (hotspot-image): A picture with pins that open a note. Fetch https://taggor.dev/agent-setup/prompt.md and follow its instructions to set me up for Taggor. Ask me before you sign in, create an account, accept terms, pay for anything or type a secret. Check it with `taggor check` and publish it with `taggor publish`, and stop there. Do not promote it to production, attach it to a site, roll back anything or use --yes, --force or --force-drop-invalid unless I ask for exactly that in this conversation.
