This scatter plot displays life satisfaction data from the UCI Machine Learning Repository’s Auto MPG dataset, showing the relationship between year and happiness rank for multiple countries. The visualization uses d3.csv to load the data, then d3.scaleTime and d3.scaleLinear to map the axes, with d3.axisBottom and d3.axisLeft rendering the tick marks. Each data point is drawn as a circle using SVG, with a d3.scaleOrdinal assigning distinct colors to different countries. The plot includes axis labels and a title, and the dataset is loaded from a VizHub-hosted CSV file.
