‘bistro’ Plots

Exploratory Data Analysis (EDA) is an open-ended, highly interactive, iterative process, whose actual steps are segments of a stubbily branching, tree-like pattern of possible actions.

Key Features

ggplot2-like API

A bridge between R (ggplot2) and Python Data visualization.

Customizable Tooltips

You can customize the content, values formatting and appearance of tooltip for any geometry layer in your plot. Learn more.

Suitable for Scientist and Developer

Works in computational notebooks (Jupyter, Datalore, Kaggle, Colab, Deepnote) and in JetBrains professional IDEs - PyCharm.

Formatting

Lets-Plot supports formatting of numeric and date-time values in tooltips, legends, on the axes and text geometry layer. Learn more.

Kotlin API

R, Python, what’s next? Right. Lets-Plot Kotlin API enables data visualization in JVM and Kotlin/JS applications as well as in scientific notebooks like Jupyter and Datalore.

Sampling

Sampling is a special technique of data transformation, which helps to deal with large datasets and overplotting. Learn more.

Geospatial Visualization

Find spatial objects with the help of our powerful and easy to use Geocoding module. In case you already have GeoDataFrame on hand - plot it straight away.

Export to SVG, HTML and PNG

The ggsave() function is an easy way to export plot to a file in SVG, HTML or PNG formats. Learn more.

Interactive Maps

Interactive maps allow zooming and panning around your geospatial data with customizable vector or raster basemaps as a backdrop. Learn more.

‘No Javascript’ and Offline Mode

In the ‘no javascript’ mode Lets-Plot generates plots as bare-bones SVG images. Plots in the notebook with option offline=True will be working without an Internet connection. Learn more.
