## What it is
GraphSketcher is a fast, simple graph drawing and data plotting application for Mac OS X and iPad, originally developed by Robin Stewart and The Omni Group and open-sourced in 2014. It lets users quickly sketch sharp-looking graphs for reports, presentations, and problem sets without needing pre-existing data.

## Use cases
- sketch graphs quickly for reports and presentations
- plot data on a Mac or iPad
- create graphs for problem sets without needing a dataset
- produce sharp-looking charts on the fly
- build a graphing app from open-source Objective-C code

## When to choose
- you need a simple, elegant tool for sketching graphs on macOS or iPad
- you want to study or fork an open-sourced Omni Group Objective-C app
- you need graphs for reports or problem sets without importing data

## When to avoid
- you need actively maintained software with recent updates or support
- you need programmatic or automated chart generation
- you need a cross-platform or web-based plotting tool
- you cannot build with Xcode 5.1 or lack code signing identities
