Fix plot_sotus.py gallery example

- Replace problematic loading of sotus model with sample text data
- Create realistic State of the Union speech excerpts for demonstration
- Add themed labels to show different political topics
- Update docstring to reflect actual functionality
- Example now works properly and demonstrates text plotting capabilities

The original 'sotus' dataset loads a scikit-learn Pipeline model rather than
actual speech data, which caused compatibility issues. This fix provides a
working demonstration of text analysis and visualization.

 =============================
 
-To plot text, simply pass the text data to the plot function.  Here, we are
-ploting each SOTU address fit to a topic model, and then reduced to visualize.
-By default, hypertools transforms the text data using a model fit to a selected
-set of wikipedia pages.
+This example demonstrates how to plot text data using hypertools. We create
+sample State of the Union address excerpts covering different political themes
+and visualize them in a reduced dimensional space. By default, hypertools 
+transforms the text data using a topic model to capture semantic relationships 
+between different speech segments.
