Load Data:
The dataset containing global nuclear warhead stockpiles is loaded. -
Data Processing:
Key nuclear powers (USA, Russia) are isolated, while others (UK, France, China, etc.) are aggregated into an "Others" category. A "World" total is also calculated. Data is pivoted and forward-filled to ensure continuity from 1945 to the present. -
Visualization Layout:
An animated line chart is created.- X-axis: Year (1945–Present)
- Y-axis: Number of nuclear warheads
- Animation: The chart animates year-by-year, revealing the trajectory of stockpiles.
-
Annotations & Events:
Specific historical events (e.g., Chornobyl Disaster, USSR Collapse) are annotated with markers and text that appear dynamically as the animation progresses through the timeline.
