import dshelper
dshelper.dshelp(df)

Feature

  • Default view with raw data and its statistics info
  • Drag on the header to re-arrange columns

  • Plots: histogram, heatmap, correlation, scatter, box, violin, pair
  • Bottom right buttons to hide panels and focus on data set
  • Easy to see memory usage and logs in bottom status bar
  • Easy to use in command line, jupyter notebook and docker

Plots

  • Histogram
  • Heatmap
  • Correlation
  • Scatter Plot
  • Box Plot
  • Violin Plot
  • Pair plot

Demo with Titanic data

The default view, main panel displays the dataset. The bottom panel displays the statistics of the dataset The right panel has two tabs, the first one displays the stats for all the columns, the second one displays the system logs.

Main View

The bottom and right panels can be hidden by clicking the buttons located on the bottom right of the window. This will allow data scientists to focus on the dataset and plots

Focus View

You can also drag and drop to re-arrange the column orders, click on the right column tab to hide columns in the main view.
