       | Hello HN. I've always found writing data visualisation scripts
       | boring and repetitive in data science workflows earlier in my
       | career, so I built this tool to automate it. The available
       | methods are based on my experience in econometrics where
       | histograms and scatterplots were the starting points to check
       | data distributions.
       | 
       | The link is to the documentation and the app is freely available
       | at https://visprex.com, and if you're curious about the
       | implementation it's open source at
       | https://github.com/visprex/visprex. I'd appreciate any comments
       | and feedback!

       | Very cool stuff!

       | Maybe bar / beeswarm charts would be useful?
       | 
       | I was missing the possibility to show differences by category, eg
       | mpg by make in the cars dataset.

       | I loaded a CSV with one date/time column and one numerical
       | column. I then selected "Scatter Plot", but got the message "Not
       | enough numerical columns found. Load a CSV file with at least 2
       | numerical columns in the Datasets tab." I would have thought that
       | a date/time column would count?

         | Thanks for trying it out! This is unfortunately not possible as
         | of now and is one of th high-priority tasks to parse timestamps
         | and datetimes, which is now incorrectly parsed as a string
         | (Categorical). I'm using Papa Parse to load CSV data and I will
         | likely need to add a custom parser on top of it.
         | 
         | Some of those plans are mentioned in my blog post reflecting on
         | building this app:
