Timeline Creator/Editor

Timeline Creator

multi-track · vertical

Canvas is view-only. The timeline on the right only renders data — zoom, pan and hover to inspect. Every add / edit / delete happens here in this panel.

Timeline range

Title

Start year

End year

Event Types 0

Each type becomes a parallel vertical track (lane) on the canvas.

Custom Fields 0

Decide your own attributes for entries — add as many as you like. They are included in the JSON export and restored on import.

Events 0

Import / Export

JSON keeps everything in sync — timeline settings, event types, custom fields and every entry with its attribute values are exported and imported together. Structure: settings, eventTypes, customFields, events[] (each event has typeId, year/month/day and an attributes map keyed by field id). PNG / PDF render the full timeline at a fixed high resolution, independent of your zoom, pan or screen — so the output looks identical on every device. Your work is auto-saved in this browser.
Embed in Blogger: paste this whole file into an HTML/JavaScript gadget (or a Page in HTML view) — the built-in override styles hide the blog's theme and render the app full-screen.
