## What it is
Kajero is a JavaScript library for creating interactive notebooks that are just Markdown documents with executable JavaScript code blocks attached. It visualizes code block return values with automatic graphing via D3, NVD3, and Jutsu, and supports publishing notebooks as Gists.

## Use cases
- create interactive javascript notebooks in the browser
- visualize data from javascript code blocks with charts
- turn markdown documents into executable notebooks
- publish a notebook as a gist with a unique url
- fetch external data sources into notebook code blocks
- generate html notebooks from markdown files on the command line

## When to choose
- you want lightweight, markdown-based interactive notebooks with built-in charting
- you want notebooks editable and shareable entirely in the browser
- you prefer plain Markdown as the notebook format

## When to avoid
- you need an actively maintained tool - the last release was in 2017
- you need rich notebook features like Jupyter's kernels or cell state
- you need Python, R, or other language support

## Facets
- artifact type: library
- maturity: abandoned
- function: data-visualization, charts, markdown, developer-tools
- domain: data-visualization, web-development, developer-tools
- platform: browser, cli
- tags: notebook, interactive-notebooks, d3, javascript-notebook, gist-publishing, nodejs, web-server
