This scatter plot visualizes Palmer Penguins data, showing the relationship between bill length and flipper length with each of three species represented by a distinct D3 symbol shape (circle, cross, triangle). The visualization uses d3.csv for data loading and filtering, d3.scaleLinear for position scales, and d3.scaleOrdinal with d3.symbol generators to map species to shapes. SVG is the rendering approach, with gridlines generated via d3.axisBottom and d3.axisLeft tick sizing. A legend created with d3.symbol identifies each species.
