DV vizualization 1
This visualization displays the physical characteristics of planets in SVG using D3.js v6. It loads planetary data from a CSV file and maps each planet’s Diameter to a linear scale, `d3.scaleLinear`, for potential horizontal positioning. The code initializes an SVG canvas with fixed dimensions and sets a white background, while the rendered output remains incomplete as data loading and drawing logic are only partially implemented. The visualization relies on D3’s selection and scale APIs, with styling defined in an external CSS file.
