📦 installation

install package using uv (recommended)

uv add -U pandas-plots

use in python source

from pandas_plots import tbl, pls, hlp, const

🚀 features

• table utilities (tbl): style dataframes as HTML tables with heatmaps, totals, kpi indicators, and percentages; describe column distributions with a single call
• plotting functions (pls): plotly-based box plots, histograms, stacked bars, sankey diagrams, upset plots, facet charts, and more
• helper functions (hlp): configure rendering for markdown export, cascade duckdb filters with counts, notebook and file utilities
• cli (cli): convert Jupyter notebooks to Markdown or HTML for publishing

📤 publishing

[!TIP] this package enables .ipynb publishing:

• converts notebooks to markdown or html
• styled pandas tables are rendered as images, retaining all features
• images can be scaled for better visual impression
• supports github and gitlab anchors
• supports github auto theme (theme="system")
• supports alternative texts in images
• html output can use image folders or inline base64 encoding
• supports easy csv export of diagram data
• can force pdf friendly options to avoid pdf artifacts

notebook setup

call hlp.setup_rendering() at the top of your notebook to configure alle rendering settings:

# src/my_notebook.ipynb

from pandas_plots import hlp

hlp.setup_rendering(
    static=True,           # True for static rendering, False for interactive
    apply_dark_theme=False
)

convert to markdown

# src/convert.ipynb

from pandas_plots.cli.converter import jupyter_to_md

jupyter_to_md(
    path="src/my_notebook.ipynb",
    output_dir="./docs",      # output folder (created if missing)
    no_input=True,            # strip input cells from output
    execute=True,             # re-execute notebook before converting
    theme="system",           # None | "light" | "dark" | "system"
    chrome_path="/Applications/Chromium.app/Contents/MacOS/Chromium"  #  path to `ungoogled-chromium` binary
)

convert to html

from pandas_plots.cli.converter import jupyter_to_html

jupyter_to_html(
    path="src/my_notebook.ipynb",
    output_dir="./docs",
    no_input=True,
    execute=False,
    use_base64=False,  # False = images in separate folder, True = inline base64
)

[!WARNING] conversion requires ungoogled-chromium installed, normal chromium wont work anymore (see prerequisites section below)

# show venn diagram for 3 sets
set_a = {'ford','ferrari','mercedes', 'bmw'}
set_b = {'opel','bmw','bentley','audi'}
set_c = {'ferrari','bmw','chrysler','renault','peugeot','fiat'}

_df, _details = pls.plot_venn3(
