Testing your apps

You're working on a custom data visualization tool for your team using Replit. After crafting a solid prompt, the AI assistant generates a polished-looking version 1 of the app. It includes CSV uploads, chart rendering, and interactive filtering.

Here's the prompt you used.

I’d like to build a data visualization tool for business reporting. The tool should allow me to upload a CSV file, automatically detect columns, and generate interactive charts (bar, line, scatter, pie). It should also allow me to filter and slice the data dynamically and export the visualizations as PNG or PDF.

Make the tool minimalist and on-brand with my company. It should feature dark mode with the following accent colors: #4CAF50.

Do research on modern dashboard and visualization tools (inspiration from Looker, Tableau, and Google Data Studio). Structure the UI for readability, use Inter as the font, and ensure responsive design for desktop and tablet.

Ensure the interface is intuitive, supports drag-and-drop CSV upload, and provides smooth animations when switching chart types or applying filters.

Now it’s time to test what Replit produced. Before sharing the app with others or refining your prompt, what should you test?
