timelinize

timelinize is an open-source tool for creating rich, shareable timelines from structured data sources (like YAML, CSV, or JSON) that helps users transform static event lists into beautiful, interactive narratives suitable for presentations, documentation, or educational displays. The project emphasizes simplicity and flexibility by letting contributors focus on the data — defining dates, labels, descriptions, links, and media — while timelinize handles rendering, layout, and interactivity in a polished browser experience. It supports multiple visualization styles, such as chronological horizontal views and compact vertical modes, so you can tailor output to fit different screen sizes and content density. With automatic linking between events and optional categories or tags, timelines become easier to navigate and filter for large datasets, making this tool practical for history projects, product roadmaps, research archives, or personal journals.
