Load your dataset

To get started on your visualisations, you should first see the Datasets tab on visprex.com. For demonstration purposes, you can also choose from publicly available example datasets.

Data format

Visprex currently only supports CSV files. Your CSV file should be delimited by commas, and the end of each row should be followed by a new line.

First line of the file should have a header which indicates the names of columns (your features).

Data types

Your CSV file will be automatically parsed as one of two data types.

Numerical: integers and floats (e.g 100, 3.14)
Categorical: string values (e.g "male", "autumn")

Once your data is loaded, this information is shown in the bottom part of the Datasets tab, where each column is assigned an index in order of appearance in the first line of your CSV file along with their inferred data type.
