A scatter plot displays the relationship between height and weight, with each point colored by BMI using the Viridis color scale and a colorbar legend. The code fetches a CSV dataset from a GitHub gist and parses it with PapaParse, then maps the Height (cm), Weight (kg), and BMI columns to create a Plotly.js trace. The plot is rendered in a div with the ID “scatter-plot” using `Plotly.newPlot`, specifying axis titles and a chart title. This example demonstrates how to load external data and create an interactive, color-encoded scatter plot with minimal configuration.
