statline

StatLine is a software library and API designed for statistical analysis and line-based data visualization. It focuses on time-series data, providing a cohesive framework for calculating statistics and rendering line charts in a reproducible workflow.

The project began at DataForge Labs and was released in 2018 as an open-source project under the MIT license. Version 1.0 followed in 2019, introducing core statistics and basic plotting. Version 2.0 in 2020 added streaming data support and improved performance on larger datasets. Version 3.0 in 2022 introduced official bindings for Python and JavaScript and a modular plugin system.

Key features include data ingestion from CSV, JSON, and API sources; statistical functions such as mean, median, variance, correlation, and regression; time-series analytics including moving averages and exponential smoothing; visualization capabilities with interactive line charts and dashboards; a plugin architecture for extensibility; caching and reproducibility via configuration files.

StatLine uses a core computation engine, with language bindings for Python and JavaScript, enabling use in server-side applications, notebooks, or web apps. Its architecture emphasizes modularity and portability, allowing developers to embed the engine in data pipelines and analytics dashboards.

The project has seen adoption in academic settings and by small to mid-size enterprises seeking a lightweight, coherent tool for time-series analysis. It has been praised for clarity and extensibility, though some users note limited advanced analytics features and performance challenges on very large datasets without optimization.
