I believe the total features and the total instances are switched

Hi,

First of all, thank you so much for maintaining this repository. I've used some of your dataset in my projects.

However, I think there's a little mistake about the information stated in the Wikipedia Math Essentials dataset.

In the information part, it's said that there are 731 instances and 1067 features. However, after looking more closely at the data, I found from the node_ids that the dataset has 1067 pages or topics. Meanwhile, each page has a daily visitor record starting from March 2019 to 2021, thus 731 days. Additionally, the dataset has stated that the time period is 731.

Please let me know if I'm missing something. Thank you.
