Happymeter: Decoding Happiness is a interactive data visualization that provides an advanced platform that distills the multifaceted metrics of the World Happiness Report 2024 into comprehensible graphical representations. Users are presented with an initial graph ranking countries based on their happiness index, derived from a three-year average score spanning 2021-2023.

For a deeper dive, the visualizer presents a second graph in a packed circles format. Users can toggle between two views: "Highest Happiness Metric Scores" and "Lowest Happiness Metric Scores". The "Highest Happiness Metric Scores" view showcases countries excelling in each of the seven key metrics, whereas the "Lowest Happiness Metrics Scores" view highlights those ranking at the bottom for each parameter.

For an enhanced geographical perspective, the third graph provides a map view, allowing users to pinpoint countries excelling or lagging in each of the seven key metrics on a global scale.
