Project Primer: Interactive Data Visualization

Origins

An interactive chart of historical financial data with hover details and zoom, created in JupyterLab using pandas and Plotly. One of the earliest projects on the site (2021).

Structure

• Jupyter Notebook published on Gist
• Data scraped from Yahoo Finance and Macrotrends using yfinance, requests, and BeautifulSoup4
• Exported as HTML (public/html/apple_interactive.html) and embedded via iframe
• Plotly range sliders for zoom and panning

Agent Guidance

• One of the site's oldest projects — predates the AI focus
• Python/Jupyter-based data science workflow
• The embedded HTML approach is the same pattern used by Energy and Roads
