Data flow diagram creation in MS Visio

I need help with a Programming question. All explanations and answers will be used to help me learn.

Hi,

I need you to create a context diagram in MS visio. (I will provide the details of all inputs in the diagram). Just need help from someone in putting things together in Visio

Your Context Diagram must address the following requirements:

• The inventory management system as the single, central Process (Processes are noun-related).
• A minimum of 3 External Entities (External Entities are noun-related).
• A minimum of 1 input data flow and 1 output data flow per External Entity (Data Flows are noun-related).
• Utilize Gane and Sarson symbols.
• Submit your Context Diagram in VSDX file format.
