Generate simple flowchart style diagram - Web Page

I am looking for a freelancer (ideally Python but ASP dot Net is also okay.) to help me generate a simple flowchart style diagram in a web page, which will be data driven (dynamic). The primary purpose of the diagram is to organize information in a logical/hierarchical way in the web page. For example: There will be two database tables 1. Employee (Data fields: EmployeeName, EmployeeID) and 2. Salary (EmployeeID, SalaryAmount) that need to be displayed on the web page and also to be connected by a line or a curved line or any other line connector. Ideal skills and experience for this job would include: - General Experience in creating flowcharts and diagrams - Understanding of entity relationship diagram - Proficiency in programming software such as Python or ASP Dot Net - Attention to detail and ability to deliver high-quality work on time. Thank you.
