## Overview

lasviewer is a Streamlit LAS-file viewer and indexer. A user can load LAS data directly or view an indexed dataset; indexing parses the file, derives curve metadata and statistics, and writes Parquet plus JSON metadata. The app supports curve plots, crossplots, histograms, and comparison of curves across two wells. For indexed viewing, it reads selected curves from Parquet before plotting. The app excerpt is partial, so some UI-to-indexing links are unverified; those are marked dashed.

Main entry points: [`app.py`](https://github.com/asergion/plotfuncao.py/blob/main/app.py) (Viewer UI), [`src/las_indexer.py`](https://github.com/asergion/plotfuncao.py/blob/main/src/las_indexer.py) (LAS indexer), [`src/analysis.py`](https://github.com/asergion/plotfuncao.py/blob/main/src/analysis.py) (Curve analysis), [`src/las_parser.py`](https://github.com/asergion/plotfuncao.py/blob/main/src/las_parser.py) (LAS parser)
