Developing visualizations with comprehensive annotations is crucial for research and educational purposes. We've been experimenting with various visualization tools like Plotly, Plotly.js, and D3.js to analyze global trends, focusing on areas such as Global Terrorism, the Global Air Quality Index (AQI), and Global Population dynamics. These visualizations help us gain insights into complex research topics, facilitating better understanding and analysis. We've created a single web homepage that links to three distinct visualization web pages, each exploring specific topics in depth. These webpages have been deployed on free cloud hosting servers such as Vercel and Render.
