This visualization gallery presents a stock market analysis hub with buttons linking to Tesla, Bitcoin, Nikkei, and Crude Oil dashboards. The Tesla page uses plain HTML buttons to navigate to separate analysis tools built with Tableau, Python, and D3. The main gallery page uses a background image and styled buttons for navigation. The D3 component would employ JavaScript data-binding and SVG rendering for interactive charts, though the linked files are not included in this snippet. The interface uses inline CSS for styling with a dark, image-backed aesthetic.
