This visualization displays Fisher's iris dataset with a dynamic scatterplot that cycles through four measured attributes. Animated circles transition smoothly between axes using D3 v7's transition framework, with `d3.scaleLinear` handling value mapping and d3.axisBottom and d3.axisLeft rendering coordinates. Each second, the x-axis switches to a new variable while y-axis remains fixed, demonstrating reusable chart components through a custom plot function.
