Creating a schema from an excel / csv file

It is necessary to automate the process of creating communication schemes, currently implemented as follows: 1) An excel file is generated with the data of the object (address, version by, number of users, etc.) 2) Using Visio, I create a diagram, link the figures of the diagram with an excel file. 3) With some periodicity, the excel file is updated, often the number of objects changes, that is, you need to delete or draw new shapes and connect them together. What do you need: The tool that created the circuit (with the ability to edit in visio / pdf) based on the source data and with the given logic connected the figures together
