Case Study 1: YouTube – Visualizing Engagement Metrics
Context:
YouTube manages billions of videos and users, with vast data on views, likes, watch time, demographics, etc. Effective data visualization helps their teams understand engagement, content performance, and user behavior.
How Visualization Is Used:

- Bar Charts: Compare the number of likes, comments, and shares across top videos.
- Heatmaps: Analyze peak engagement times during the day or week.
- Box Plots: Detect outliers in video performance (e.g., videos with sudden spikes in views).
- Geographical Maps: Visualize views by country to identify regional trends.
Case Study 2: Zomato – Analyzing Restaurant Data
