Aja jooninfograafikad, or timeline infographics, are a form of data visualization that presents events in chronological order along a time axis. They help convey the sequence and timing of events, milestones, or processes.

A typical timeline includes a horizontal or vertical axis marked with dates or time spans, event markers at points along the axis, short labels, and brief descriptions. Some timelines incorporate images, colors, or icons to differentiate categories. Timelines can be linear, segmented, or radial, and may be static or interactive.

Design considerations include choosing an appropriate time scale and granularity, avoiding clutter, prioritizing key events, maintaining consistent styling, and ensuring legibility and accessibility. When data covers long periods, grouping events by themes or categories can reduce overload. Effective timelines balance clarity with sufficient detail.

Applications include historical overviews, project roadmaps, product lifecycles, educational materials, and journalism. They are useful for showing sequence, durations, and potential cause–effect relationships. Limitations include potential overcrowding for large sets of events and the need for interactive formats to handle complex data; for some tasks, other visualizations may be more suitable. Timelines are commonly created with presentation software, graphic design tools, or specialized online platforms to support both static and interactive experiences.
