The record

Purpose: Storyline is an open-source tool for building annotated, interactive line charts that tell the story behind time-series data.
Chart type: Storyline focuses on time-series line charts, and the x-axis accepts only time or date formats.
Story cards: Stories use cards with a title, text, and date to explain selected points in the data.
Card limits: A story supports no more than 12 cards, titles are limited to 54 characters, and paragraphs to 200 characters.
Data source: To create a Storyline with the authoring tool, users put their chart data in a Google spreadsheet and publish it to the web.
Data capacity: Storyline works best with fewer than 800 data points.
Multiple series: The tool can visualize only one set of data at a time.
Publishing: Users can publish a Storyline as an embed or share it through a direct link, and the tool says it works on any site or blog.
Languages: Month names in one date-display choice are available only in English; the maker says most of the story uses language supplied by the user.
Support: The maker offers a tech support web form and GitHub issue reporting, says support is available only in English, and notes it has no dedicated tech support staff.
Security: The product page does not state security certifications or compliance claims.
Maker: Storyline JS is made by Northwestern University Knight Lab, a team of technologists and journalists working on news media innovation.
Founded: 2017
Headquarters: Evanston, Illinois, United States
