"""
Basics of styling
======================

This example shows a few simple styling options available in `iplotx`.

.. tip::
  `iplotx` has an internal library of styles. See the :doc:`plot_multistyle`
  example.

import igraph as ig
import matplotlib.pyplot as plt
import iplotx as ipx

g = ig.Graph.Ring(5)
layout = g.layout("circle")
style = {
    "vertex": {
        "facecolor": ["purple", "pink", "black"],
        "edgecolor": "black",
    },
    "edge": {
        "linestyle": "--",
        "linewidth": 2,
        "color": "deeppink",
    },
}
fig, ax = plt.subplots(figsize=(3, 3))
ipx.network(g, ax=ax, layout=layout, style=style)

# %%
# You can also **chain styles**. For example, you can apply an existing
# style first, and then modify it with a custom dictionary:

style = {
    "edge": {
        "linestyle": "--",
    },
}
fig, ax = plt.subplots(figsize=(3, 3))
ipx.network(
    g,
    ax=ax,
    layout=layout,
    style=["rededge", style],
)

# %%
# As you can see, the network is visualised with the "rededge" style (which
# has red, solid edges) but further modified to have dashed lines.
