What's New

- Add the `set_custom_palette`, `box_plot`, `kde_plot`, `probability_plot`, `bar_plot`, `regression_plot` and `plot_correlation` functions (See [Plotting Examples][plotting]).

- Rename `target_variable` to `groupby_data`:
- Select a more intuitive name. Target_variable is ambiguous.
- Add the groupby [-g, --groupby] cli arg.

- Update document layout:
- Center-align images and tables.
- Reduce unnecessary page-breaks.

- Replace correlation heatmap with a bar chart:

Show coloured & labeled bars of the top 20 correlated numeric variable pairs (by magnitude). Makes it much easier to notice highly correlated variables.

- Limit bivariate summaries & regression plots to 50.

Necessary since combinations blow up quickly. 50 numeric columns could easily result in a 500 page report, taking ages to prepare (`combination(50_numeric_cols, 2) == 1225` pairs, and 1 page == 2 pairs). Now only the top 50 pairs will be published (approx 25 pages).

- Configure color in each subprocess:

Update helper functions to accept color choice, and set custom palette. Spawned subprocesses (Windows & Mac currently) weren't getting the globally modified colors.

- Reduce graph image dpi from 250 to 150:

Results in smaller, but very decent images. Significantly reduces the size of report documents with many variables.

- Revise correlation interpretation.

Use R.H. Evans (1966) guide:

.00-.19 -> very weak
.20-.39 -> weak
.40-.59 -> moderate
.60-.79 -> strong
.80-1.0 -> very strong

- Fix handling of int values for `groupby` specifier:
- Int input from the cli and gui is parsed as a string, and failed the `isinstance(x, int)` test.
- The `str.isdecimal` test is more suitable here.

- Optimize tests:
- Add conftest.py.
- Add a session-level temp_data_dir fixture.

**Full Changelog**: https://github.com/Tim-Abwao/eda-report/compare/v2.6.0...v2.7.0

What's Changed

* Use `StringDtype` for text & mixed data. Fixes 16 (in 18)

`object` dtype causes errors when sorting mixed numeric+text data.
* Drop completely empty columns. Fixes 17

Update data validation to drop columns full of `NaN`.
Empty columns caused a fatal error by breaking analysis functions.
