styles VS altair-latimes

To use any of the themes available in the three examples mentioned above globally, we need to alt.themes.register() and alt.themes.enable() them. In the case of the carbonplan-styles package, which provides a light theme and a dark theme for Altair and Matplotlib, we just need to enable the theme (and we don't need to import any extras). In other words, there is no need to register the theme, as it is added to the available themes "automatically" from the entry points defined in the setup.py file (or equivalent):

Based on the altair-latimes package, we have altair-reveal. In this package, we can find the Reveal theme for Altair. An interesting detail in this theme is the empty space available at the bottom of each chart (bottom padding) to accommodate manually added sources and credits. We can see this detail, as well as several examples, from this notebook directly on GitHub.

As a first example, we have the altair-latimes package. Here we can find the Los Angeles Times theme for Altair. More specifically, in addition to the theme() function that contains some constants and returns a dictionary with the configuration for the theme, there is a color dictionary (palette). This color dictionary can also be imported and used directly.
