History Timeline
Scroll a horizontal timeline with several history lanes at once. Add, remove, or drag-reorder the rows, set a lane’s color in its config, zoom from millennia to days, and let missing spans fill as you pan. Seeded events show immediately; Grok writes the blanks and MongoDB remembers the window.

How to practice
Scroll left for the past, right for the future. Add a lane from the dropdown, drag the grip to reorder, or remove it with ×. The gear opens color and rename. Zoom from millennia through days. Lanes, colors, zoom, and scroll restore on reload. A new custom lane starts filling for the window you are looking at.

Left is the past, right is the future. Empty stretches fill as you pan with Grok. Seeded events are ready.
