Companion to the maintenance update of Interactive Data Visualization in Python With Bokeh (post 211).

What changed

• bokeh-template.py, east-west-tabbed-layout.py: import TabPanel, Tabs from bokeh.models (Bokeh 3.0 renamed Panel to TabPanel and moved it out of bokeh.models.widgets); plot_width -> width.
• first-figure.py: plot_height/plot_width -> height/width; drop the removed h_symmetry property.
• first-glyphs.py: height/width; circle(size=...) -> scatter(size=...) (deprecated since Bokeh 3.4).
• multiply-glyphs.py: height/width; legend= -> legend_label=.
• README.md: Kaggle links moved to /datasets/pablote/nba-enhanced-stats (old paths 404).

These mirror exactly the code blocks fixed in the article draft. The rest of the snippets (CDSView filters, remaining plot_width/legend= uses) are still on the Bokeh 1.x API; the card is routed to a full update, which will port them.

Verification

• bokeh-template.py, first-figure.py, first-glyphs.py, multiply-glyphs.py run cleanly on bokeh 3.10.0 / pandas 3.0.6 / Python 3.14.
• east-west-tabbed-layout.py depends on figures from earlier snippets; its API (TabPanel, Tabs, .width) was exercised on bokeh 3.10.0 with stand-in figures.
• uvx ruff@0.14.1 format --check intro-to-bokeh and uvx ruff@0.14.1 check intro-to-bokeh pass.
