Draw pretty maps from OpenStreetMap data! Built with osmnx +matplotlib + shapely

README at capture

# prettymaps

A minimal Python library to draw customized maps from [OpenStreetMap](https://www.openstreetmap.org/#map=12/11.0733/106.3078) created using the [osmnx](https://github.com/gboeing/osmnx), [matplotlib](https://matplotlib.org/), [shapely](https://shapely.readthedocs.io/en/stable/index.html) and [vsketch](https://github.com/abey79/vsketch) packages.

# Installation

### Install locally:
Install prettymaps with:

```
pip install prettymaps
```

### Install on Google Colaboratory:

Install prettymaps with:

```
!pip install -e "git+https://github.com/marceloprates/prettymaps#egg=prettymaps"
```

Then **restart the runtime** (Runtime -> Restart Runtime) before importing prettymaps

# Run front-end

After prettymaps is installed, you can run the front-end (streamlit) application from the prettymaps repository using:
```
streamlit run app.py
```
# Tutorial

The full tutorial is at **[docs/tutorial.md](docs/tutorial.md)** — a markdown walkthrough with rendered images, the `[Plot]` dataclass fields, the `layers`/`style` parameters, presets, multiplot, hillshade, and keypoints.

![Heerhugowaard sample](docs/img/tour-01-heerhugowaard.png)

**Quick start:**

```python
import prettymaps

plot = prettymaps.plot('Stad van de Zon, Heerhugowaard, Netherlands')
```

| Resource | Where to find it |
|---|---|
| Full tutorial (markdown + images) | [`docs/tutorial.md`](docs/tutorial.md) |
| Interactive marimo notebook (runnable) | [`notebooks/tutorial.py`](notebooks/tutorial.py) |
| Open in Google Colab | [Open in Colab](https://colab.research.google.com/github/marceloprates/prettymaps/blob/master/notebooks/tutorial.py) |
| Streamlit front-end | `streamlit run app.py` |

### Run the tutorial locally (marimo)

```sh
# Install marimo (already in requirements.txt)
pip install marimo

# Open the notebook in your browser
marimo edit notebooks/tutorial.py
```

### Customizing parameters

The most important `prettymaps.plot()` parameters are:

- **`layers`** — dict of OpenStreetMap layers to fetch.
- **`style`** — dict of matplotlib style parameters per layer.
- **`preset`** — load a JSON preset (e.g. `'default'`, `'minimal'`, `'macao'`, `'tijuca'`).
- **`circle`** / **`radius`** / **`dilate`** — boundary shape.

`plot` is a dataclass with `geodataframes` (per-layer GeoDataFrames), `fig`, and `ax`.

```python
plot = prettymaps.plot(
    'Praça Ferreira do Amaral, Macau',
    circle=True,
    radius=1100,
    layers={
        "water": {"tags": {"natural": ["water", "bay"]}},
        "building": {"tags": {"building": True}},
    },
    style={
        "water": {"fc": "#a1e3ff", "ec": "#2F3737"},
        "building": {"palette": ["#FFC857", "#E9724C", "#C5283D"]},
    },
)
```
