What is the difference between tawa roti and chapati?

Can you explain the distinction between tawa roti and chapati? I've heard they're both types of flatbread, but I'm not sure how they differ in terms of their ingredients, preparation methods, or even their cultural significance. Are there any noticeable differences in taste or texture between the two? I'd appreciate a clear and concise explanation to help me understand the nuances between these two popular Indian dishes.
