Frequently Asked Questions (FAQ)
Q: Do I need to build my own backend for my application?
A: Not necessarily! As explained at (10:40), CARTO serves as your geospatial backend. Our APIs connect directly to your data warehouse, handling the computation and data retrieval so you can focus on the front-end experience.

Q: How does this architecture handle massive datasets?
A: All heavy computations happen directly in your cloud data warehouse (like Snowflake, BigQuery, Databricks, or Redshift). As shown in the demos (11:18, 54:24), this allows you to interactively analyze millions or even billions of records with sub-second response times, without crashing the user's browser.

Q: What charting libraries can I use for my widgets?
A: You have complete freedom! CARTO is library-agnostic, meaning you can use your team's favorite charting tools like ECharts, D3.js, Chart.js, or any other library (26:43).

Q: Do you provide templates for frameworks like React, Angular, or Vue?
A: Yes! We have official CARTO App Templates to help you get started immediately. You can find them here: https://github.com/CartoDB/carto-app-...
