Haze - Bokeh visualization for interactive stack project

What's Haze

Haze implements a DSL within Haskell, having BokehJS (see Bokeh) as the transpiling target, for Haskell code to do low-level plotting (in contrast to more declarative, high-level charting).

Advantage over other Visualization Kits for Haskell

Size & Speed in essence.

• Actuall data are always transfered & used as binary chunks, much more efficient than solutions with intermediate representations in textual (commonly JSON in particular) form. This unleashes Bokeh's potental of rendering massive data points at the order of millions, while still being smooth, as well as previewed, during continuous scaling (zoom) / dragging (pan) and etc. BokehJS achieves these by rendering with WebGL beyond HTML Canvas, or simply SVG.

• You can interactively visualize the massive result data of your Haskell code during active development of the projects, for immediate verification & intuition, thus fast iterations.

• WYSIWYG. The live plot setup, with whatever arguments it takes, is right-away published over network, i.e. made available to others in reach. But you want to do this only within a trusted internal environment, given this security CAVEAT by far still valid. The stack project underhood is straight to be versioned and released from coding team to analyzing team as a deliverable across the production lifecycle.

Style

BokehJS aims to be declarative compared to traditional graphical programming toolkits, but it still feels imperative compared to stylish Haskell.

Haze just lifts the imperative aspect of BokehJS API into Haskell for now, it might have more potental to improve, let's see how's that over time.

Documentation

Haze lacks documentation as badly as BokehJS does, best doc may be the (unfortunately Python oriented) API reference.

While fortunately it'll feel language-neutral once you get familiar with Bokeh at all, the reference sorta works for all languages relevant, i.e. TypeScript (JavaScript), Python, and more languages listed at https://docs.bokeh.org/en/latest/docs/dev_guide/bindings.html

Design

Haze works as a Hadui overlay.

Haze deviates from the strongly typed tradition pursued by both Bokeh (written in TypeScript at the core) and Haskell, for time being. It may possibly become a full-fledged, strongly typed Haskell binding of Bokeh ultimately, but however not for certain right now.
