This 3D scatter plot visualizes the World Happiness Report data for six countries, showing the relationship between Life Ladder scores, Social Support, and both Positive and Negative Affect. The visualization displays two marker types: orange circular markers for positive affect and gray square markers for negative affect. The code uses the Plotly.js library through the `Plotly.newPlot` function to render the interactive 3D chart, while D3.js handles data loading from a CSV file hosted on GitHub using `d3.csv`. The data is parsed and unpacked into trace objects defined with the `scatter3d` type.
