A D3-based library for building interactive financial charts with technical analysis indicators.
TechanJS is a JavaScript library built on D3 for creating interactive financial charts and technical analysis visualizations. It provides tools to plot candlestick, OHLC, and volume charts, along with a suite of technical indicators like moving averages, RSI, and MACD. The library solves the need for a flexible, reusable charting solution tailored to financial data analysis.
Developers building trading platforms, financial dashboards, or market analysis tools that require interactive, technical charting capabilities. It's ideal for those familiar with D3 who need specialized financial visualization components.
Developers choose TechanJS for its deep integration with D3, offering a reusable chart API pattern that ensures consistency and extensibility. Its comprehensive set of financial-specific plots and indicators, combined with interactive features like crosshairs and zooming, provides a robust alternative to generic charting libraries.

Built on D3, it allows for highly customizable and extensible charting, evidenced by the reusable chart API pattern emphasized in the README.
Includes essential financial plots like candlestick and OHLC charts, plus a wide range of technical indicators such as RSI, MACD, and Ichimoku Cloud, directly from the examples.
Supports crosshairs, trendlines, and zooming for dynamic data exploration, with dedicated interactive plot examples provided in the README.
Follows D3's reusable chart pattern, promoting consistent and maintainable code structure, as highlighted in the philosophy section.
Relies on D3, increasing bundle size and requiring familiarity with D3's API, which adds complexity compared to standalone charting libraries.
The README warns that the master branch may contain unstable features not always compatible with examples, posing risks for production use without careful versioning.
Building examples requires recursive cloning and npm setup, with additional steps for Docker, making initial exploration more cumbersome than plug-and-play libraries.
