World Happiness Scores by Population
This visualization displays world happiness scores and population sizes on a natural Earth projection map, with each country represented by a circle whose area encodes population and color encodes happiness score. Users can pan, zoom, and hover to see country names and scores, while clicking reveals additional details. The visualization uses d3.geoPath, d3.geoNaturalEarth1, d3.zoom, and d3.scaleSqrt for population scaling, with happiness data from the World Happiness Report. A color legend and size legend clarify the mapping, and the rendering is SVG-based.

A country’s overall happiness score is a composite of different factors collected in an annual worldwide survey, including:
GDP per capita School years Sustainable economic development Employement Rate Health expenditure Government effectiveness Female MPS Control of corruption
What factors contributes to happiness for different countries is interesting. For example more school years increases happiness in certain countries, it's probably correlated with more salaries when a person studies more. I need to create another visual to show the relationship between each factors for each country.
