In plain words

Empirical is a programming language designed specifically for time-series analysis. It treats dataframes as standard values and includes variables, types, and functions for working with temporal data. The language allows users to load and manipulate datasets like trades, quotes, and events through a straightforward syntax. Empirical is intended for analysts and developers who need to perform time-series computations and data transformations efficiently.

    Hello HN. I've always found writing data visualisation scripts boring and repetitive in data science workflows earlier in my career, so I built this tool to automate it. The available methods are based on my experience in econometrics where histograms and scatterplots were the starting points to check data distributions. The link is to the documentation and the app is freely available at https://visprex.com, and if you're curious about the implementation it's open source at https://github.com/visprex/visprex. I'd appreciate any comments and feedback!
