ggsql-jupyter 0.1.8

Jupyter kernel for ggsql - SQL extension for declarative data visualization

ggsql Jupyter Kernel

A Jupyter kernel for executing ggsql queries with rich inline Vega-Lite visualizations.

Overview

The ggsql Jupyter kernel enables you to run ggsql queries directly in Jupyter notebooks, with automatic rendering of visualizations using Vega-Lite. It maintains a persistent DuckDB session across cells, allowing you to build up datasets and create visualizations interactively.

Features

• Execute ggsql queries in Jupyter notebooks
• Rich visualizations with Vega-Lite rendered inline
• Persistent DuckDB session across cells
• Pure SQL support with HTML table output
• Grammar of Graphics syntax for declarative visualization

Installation

Prerequisites

• Jupyter Lab or Notebook installed

Option 1: Install from PyPI (Recommended)

The easiest way to install the ggsql kernel is from PyPI. This provides pre-built binaries for Linux, macOS, and Windows.

Using pip:

pip install ggsql-jupyter
ggsql-jupyter --install

Using uv:

uv tool install ggsql-jupyter
ggsql-jupyter --install

The --install flag registers the kernel with Jupyter. It automatically detects and respects your current environment (virtualenv, conda, uv, etc.).

Option 2: Install from crates.io

Requires a Rust toolchain:

cargo install ggsql-jupyter
ggsql-jupyter --install

Option 3: Download Pre-built Binary

Pre-built binaries are available from GitHub Releases:

Platform	Binary
Linux (x86_64)	ggsql-jupyter-linux-x64
Linux (ARM64)	ggsql-jupyter-linux-arm64
macOS (Intel)	ggsql-jupyter-macos-x64
macOS (Apple Silicon)	ggsql-jupyter-macos-arm64
Windows (x64)	ggsql-jupyter-windows-x64.exe

After downloading, make it executable and install:

chmod +x ggsql-jupyter-*
./ggsql-jupyter-linux-x64 --install

On Windows (PowerShell):

.\ggsql-jupyter-windows-x64.exe --install

Option 4: Build from Source

Requires a Rust toolchain. From the workspace root:

cargo build --release --package ggsql-jupyter
./target/release/ggsql-jupyter --install

Installation Flags

• --install: Install the kernel (default: user install)
• --install --user: Explicitly install for current user
• --install --sys-prefix: Install into sys.prefix (for conda envs)

Usage

Start Jupyter

jupyter lab
# or
jupyter notebook

Create a ggsql Notebook

1. In Jupyter, click "New" and select "ggsql" from the dropdown
2. Start writing ggsql queries!

Example Queries

Simple Point Plot

SELECT 1 as x, 2 as y, 'A' as category
UNION ALL
SELECT 2, 4, 'A'
UNION ALL
SELECT 3, 3, 'B'
VISUALISE x, y, category AS color
DRAW point

Time Series

SELECT
    '2024-01-01'::DATE + INTERVAL (n) DAY as date,
    n * 10 as revenue
FROM generate_series(0, 30) as t(n)
VISUALISE date AS x, revenue AS y
DRAW line
SCALE x SETTING type => 'date'
LABEL title => 'Revenue Growth', x => 'Date', y => 'Revenue ($)'

Multi-Layer Plot with Global Mapping

SELECT x, x*x as y, x*x*x as z
FROM generate_series(1, 10) as t(x)
VISUALISE x AS x
DRAW line MAPPING y AS y
DRAW line MAPPING z AS y
LABEL title => 'Polynomial Functions'

Pure SQL (Data Tables)

SELECT * FROM (VALUES (1, 'a'), (2, 'b'), (3, 'c')) AS t(id, name)

This will display as an HTML table without visualization.

Building Up Data Across Cells

Cell 1:

CREATE TABLE products AS
SELECT * FROM (VALUES
    (1, 'Widget', 10.99),
    (2, 'Gadget', 24.99),
    (3, 'Doohickey', 5.99)
) AS t(id, name, price)

Cell 2:

SELECT * FROM products
VISUALISE name AS x, price AS y
DRAW bar
LABEL title => 'Product Prices', y => 'Price ($)'
