# Polygon/Multipolygon#

## Example Polygon#

You can easily create a `Polygon` providing the list of vertex locations (in lat/lng).

```from ipyleaflet import Map, Polygon

polygon = Polygon(
locations=[(42, -49), (43, -49), (43, -48)],
color="green",
fill_color="green"
)

m = Map(center=(42.5531, -48.6914), zoom=6)

m
```

Because the `Polygon` an interactive widget, you can dynamically update the locations/color from Python, and you will see updated on the `Map`.

## Example Polygon with holes#

You can define holes in your `Polygon` by using nested lists of vertex locations.

```from ipyleaflet import Map, Polygon

polygon = Polygon(
locations= [
[(37, -109.05), (41, -109.03), (41, -102.05), (37, -102.04)],
[(37.29, -108.58), (40.71, -108.58), (40.71, -102.50), (37.29, -102.50)]
],
color="green",
fill_color="green"
)

m = Map(center=(37.5531, -109.6914), zoom=5)

m
```

## Example MultiPolygon#

```from ipyleaflet import Map, Polygon

multipolygon = Polygon(
locations=[
[(42, -49), (43, -49), (43, -48)],
[(44,-49), (43, -50), (44,-50)]
],
color="green",
fill_color="green"
)

m = Map(center=(42.5531, -48.6914), zoom=6)

m
```

## Example Editable Polygon#

If `transform` is set to `True`, you can dynamically edit the polygon with the mouse.

```from ipyleaflet import Map, Polygon

polygon = Polygon(
locations=[(42, -49), (43, -49), (43, -48)],
color="green",
fill_color="green",
transform=True
)

m = Map(center=(42.5531, -48.6914), zoom=6)
