Charter

charter is a typed Haskell layer on top of Google Charts which allows quickly and easily visualizing your Haskell data in the browser!

It also provides live-updates as your data changes in Haskell-land.

Why Google Charts?

Google Charts provides a large amount of flexible data representations which use a relatively consistent data format, making it easy to switch between chart types.

Goals

Goals of this library include:

• Quick to start
• Batteries Included
• Well-typed, but not at the expense of usability
• Smooth learning curve as you add more complex options to your charts
• Live chart updates!

Non-Goals of this library include:

• Writing charts to disk: sorry, try taking a screenshot of your browser instead!
• Performance: All your data turns into JSON and gets piped through the browser, it'll be slower than other solutions on large datasets.
• Composability with other solutions: This library is "battery included" and doesn't provide many extension points.

Roadmap

• Better Date, Time, and DateTime support
• Support for Geocharts, TreeMaps, Tables, Timeline, Gauges
• Support multiple charts on a screen
• Support combo charts
