 ## Description
 This project is a TypeScript/JavaScript application that processes RDF data to create a graph representation. It uses React for the frontend and Chakra UI for styling.
 
-We strongly suggest users to use `turtle for`mat for RDF data and `schema.org` vocabulary for the properties. The application is designed to work with the `schema.org` vocabulary, since we developed it for a specific use case. However, it can be easily modified to work with other vocabularies.
