This example demonstrates the complete removal of all data and code from a visualization. The page displays only a confirmation message, with all chart elements, SVG content, and text cleared during initialization. Using D3.js methods such as `select` and `csv`, the program removes references to data files, empties DOM elements, and strips SVG dimensions. The code references `data.csv` and `data1.csv` as the original data sources, though they are no longer loaded or processed.
