This scatter plot displays self-reported life satisfaction across the world from 2004 to 2016, mapping each country’s Happiness Rank against the year. The visualization uses D3 v5’s `scaleTime` and `scaleLinear` to position orange, semi-transparent circles within an SVG, with `axisBottom` and `axisLeft` providing labeled axes. Data is loaded via `d3.csv` from a modified World Happiness Report 2017 dataset hosted on VizHub, and the chart includes gridlines and a title annotation.
