…onsistency - Changed `quarto render` command in GitHub Actions from `--no-execute` to `--execute` for proper rendering. - Enhanced readability in `data-transform.ipynb` by removing unnecessary line breaks and simplifying code expressions. - Added missing import statement for `polars` in `data-visualise.ipynb`. - Improved code formatting and consistency across various cells in both notebooks.
- Import `lets_plot` at the beginning for clarity. - Adjust DataFrame column operations for better readability. - Simplify plot creation by using parentheses for chaining. - Remove unnecessary imports and whitespace for cleaner code.

…polars into brent-IMPORT
- Added newline characters to the end of several text blocks in `webscraping-and-apis.ipynb` to ensure proper formatting. - Adjusted the structure of code snippets for better clarity and consistency. - Removed unnecessary lines and streamlined code for better presentation.

…display for functions, and correct code snippets for clarity. Adjusted execution counts and fixed minor documentation errors.
…ith polars - Updated import statements and function calls in data-import.ipynb to use polars instead of pandas. - Adjusted text descriptions to reflect the changes from pandas to polars, including installation instructions and function usage. - Cleaned up markdown formatting for better readability. - Removed unnecessary sections and streamlined explanations in data-transform.ipynb.

Updated workflow-styles
- Added execution counts to various code cells across multiple notebooks for better tracking of code execution. - Enhanced output displays in `boolean-data.ipynb`, `categorical-data.ipynb`, `communicate-plots.ipynb`, `data-import.ipynb`, `data-tidy.ipynb`, `data-transform.ipynb`, and `data-visualise.ipynb` to provide clearer results and visualizations. - Improved overall consistency in notebook formatting and presentation.
- Updated the command line chapter in `command-line.md` to improve formatting by replacing asterisks with underscores for emphasis. - Modified output displays in `functions.ipynb` and `iteration.ipynb` to reflect new data and execution counts, ensuring consistency and clarity in results. - Adjusted various execution counts across notebooks to maintain accurate tracking of code execution.
- Updated execution counts to null and cleared outputs in `boolean-data.ipynb`, `categorical-data.ipynb`, `communicate-plots.ipynb`, `data-import.ipynb`, `data-tidy.ipynb`, `data-transform.ipynb`, and other notebooks for a cleaner presentation. - Enhanced overall consistency in notebook formatting by removing previous output displays, ensuring a more streamlined user experience.

Summary
This PR migrates categorical data examples from pandas to Polars and updates the accompanying explanations to better reflect Polars' API and behavior.
Changes
