Developed a user-facing Product Comparison Demo Page for the VisActor/VTable repository, focusing on data visualization and frontend development using JavaScript. The demo showcases a product comparison table for robot vacuum models, featuring configurable row trees and conditional background coloring to highlight differences between products. This implementation enables stakeholders and customers to interactively explore product specifications, supporting sales demonstrations, onboarding, and feature validation. The work included updating documentation in Markdown to guide users on leveraging the new demo. By delivering this feature, the developer enhanced the library’s ability to communicate its capabilities through tangible, interactive examples without addressing bug fixes.
