A scatter plot displays the relationship between two numeric variables as circles in a Cartesian coordinate system. The example loads a dataset from a CSV file named `scatter.csv` using the `d3.csv` method, then passes the parsed data to a `createScatterPlot` function that renders the visualization into an HTML container. The implementation relies on the D3.js v7 library for data loading and chart construction, though the JavaScript file defines the plotting logic separately. An error handler logs any issues encountered during the asynchronous CSV fetch.
