What is the best way to add the results of the Master thesis in the Latex report
The full data is the main outcome for the organization, but it's not an important part for your report. Of course you can show examples/samples, but what matters in your report is to explain clearly:

The motivations: why is this data generator needed? What can be done with it that couldn't be done before? This probably requires explainining the context of the work: what this organization does, what is this domain, why does it matter, etc.
The state of the art: which existing methods are used for this kind of problems in general? What are their advantages and disadvantages?
The method/process: how does it work? Provide all the details necessary the system. If you made particular implementation choices, explain why this choices and not another option. Is it related to existing methods? If yes compare to these methods.
The outcome: analyze the results in detail with statistics, graphs or whatever means helps the reader understand the characteristics of the data. It should be a synthetic overview, not a dump of the full dataset. Prove that the obtained data satisfies the requirements, for instance by comparing to other datasets. If relevant show the impact of your implementation choices through some examples.

The point of the report is to explain your work to somebody who is not an expert in this particular problem. Presenting the reasoning that you followed is much more important and interesting than the data itself.
