🚀 UltraPlot v1.70.0: Smart Layouts, Better Maps, and Scientific Publishing Support

High-Level Overview: This release focuses on intelligent layout management, geographic plotting enhancements, and publication-ready features. Geographic plots receive improved boundary label handling and rotation capabilities, while new Copernicus Publications standard widths support scientific publishing workflows. Various bug fixes and documentation improvements round out this release.

Major Changes:

1. Geographic Plot Enhancements

# Improved boundary labels and rotation
fig, ax = uplt.subplots(projection="cyl")
ax.format(
    lonlim=(-180, 180),
    latlim=(-90, 90),
    lonlabelrotation=45, # new parameter
    labels=True,
    land=True,
)
# Boundary labels now remain visible and can be rotated

2. Copernicus Publications Support

# New standard figure widths for scientific publishing
fig = uplt.figure(journal = "cop1")
# Automatically sets appropriate width for Copernicus Publications

3. Legend Placement Improvements

import numpy as np

import ultraplot as uplt

np.random.seed(0)
fig, ax = uplt.subplots(ncols=2, nrows=2)
handles = []
for idx, axi in enumerate(ax):
    noise = np.random.randn(100) * idx
    angle = np.random.rand() * 2 * np.pi
    t = np.linspace(0, 2 * np.pi, noise.size)
    y = np.sin(t * angle) + noise[1]
    (h,) = axi.plot(t, y, label=f"$f_{idx}$")
    handles.append(h)

# New: spanning legends
fig.legend(handles=handles, ax=ax[0, :], span=(1, 2), loc="b")
fig.show()
