## What it is
Sparks is an OpenType typeface that renders sparklines (bar, dot, and dot-line charts) directly in text by converting number sequences like `123{30,60,90}456` into inline charts using contextual alternates. It works on the web without JavaScript and in desktop apps like Word, Pages, and Adobe Creative Cloud.

## Use cases
- embed tiny inline charts in text without JavaScript
- add sparklines to a web page with just a font and CSS
- render data visualizations inside Word or Pages documents
- draw sparklines in SVG from live data
- display inline bar and dot charts in a blog article

## When to choose
- you need lightweight inline charts in flowing text with no JavaScript
- your data fits a fixed 0-100 scale and can be pre-normalized
- you want sparklines that work in desktop word processors and design tools

## When to avoid
- you need dynamic scales, axes, tooltips, or interactive charts
- your target browsers or apps lack OpenType contextual alternates support
- you need charts larger than a line of text
