Thanks for this. Looks perfect for my needs. I've got to analyse a hideous generated CSV file with thousands of columns. I was planning to load it into SQLite3 but it has too many columns for import. I was also unpleasantly surprised to find that the column names were too long for PostegresQL too. Python + pandas can handle it, but a tool for quick interactive exploration is just what I need. Hopefully visidata will provide!
