This visualization shows global self-reported life satisfaction from 2004 to 2017, using data from the World Happiness Report 2017. It combines a scatter plot with a line chart, letting users explore different well-being metrics via a dropdown map. The SVG rendering uses d3.scaleTime, d3.scaleLinear, d3.axisBottom, and d3.axisLeft. An animated cartoon face (built with d3.arc and transitions) reacts to the data, while a color legend and tooltips on mouseover provide interactive filtering and detail.
