Using my own datasets in Causal Discovery Toolbox

I am currently working on a web application which provides a tool to generate graphs by datasets with the causal discovery toolbox. I am stuck, because in the CDT tutorial on https://fentechsolutions.github.io/CausalDiscoveryToolbox/html/causality.html they always use their sample datasets. I am a bit confused how I can load my own datasets. Does anyone know the solution? Thank you!
