  1. Load Data:
    Official demographic data is processed to track the two historical phases of displacement: the 1986 Emergency Evacuation (116,000 people from the Exclusion Zone) and the subsequent 1987–1995 Resettlement Programs.
  2. Visualization Layout:
    A Time-Series Analysis (Line & Bar Combination) is configured to display the cumulative progression of displaced populations. The X-axis represents the timeline (1986–1995), while the Y-axis quantifies the human displacement.
  3. Styling:
    The visualization employs a dual-color scheme:
    • High-Contrast Red/Orange: Highlights the sudden spike of the 1986 emergency evacuation.
    • Neutral / Greyscale: Depicts the steady, "invisible" accumulation of resettled people in the following decade.
  4. Insight:
    The visualization reveals that the 1986 explosion was only the beginning: the data proves that migration continued for a decade, with the total number of displaced people nearly tripling (+187%) from the initial evacuation to 1995 (reaching ~333,000).
