osm_graph 0.2.0

This library provides a set of tools for generating isochrones from geographic coordinates. It leverages OpenStreetMap data to construct road networks and calculate areas accessible within specified time limits. The library is designed for both Rust and Python, offering high performance and easy integration into data science workflows.

# Installation

## Python

### From PyPI

```bash
pip install pysochrone
```

Wheels are provided for Python 3.8+ on Linux, macOS, and Windows (x86-64).

### From source

Requires [Rust](https://rustup.rs/) and [maturin](https://www.maturin.rs/).

```bash
git clone https://github.com/kyleloving/osm_graph.git
cd osm_graph
pip install maturin
maturin develop --release
```

`maturin develop` compiles the Rust extension and installs it into the current Python environment in one step.  The `--release` flag enables compiler optimisations — omit it only for debug builds.

## Rust

Add to `Cargo.toml`:

```toml
[dependencies]
osm-graph = "0.2.0"
```

> **Note:** The crate is published as `osm-graph`; the library module is `pysochrone` (matching the Python package name).

## Dependencies

pysochrone has no required Python dependencies — all heavy lifting is in Rust.

Optional Python packages used in the examples:

```bash
pip install folium branca
```
