scicloj.glance

Glance just plots your data.

scicloj.glance is a Clojure library for getting a plot on the screen with minimal ceremony. It’s a friendly on‑ramp for people who just want to see their data.

Rationale

Many users reach visualization with a simple goal:

“I have some data. I want a chart.”

Glance deliberately optimizes for:

• One function – call g/plot
• Plain Clojure data – vectors, maps, sequences
• Automatic chart inference – picks a sensible visualization
• No plotting API to learn – opens in your browser immediately

Installation

Add Glance to your project dependencies:

Usage

(require '[scicloj.glance :as g])

(g/plot [1 4 9 16])

(g/plot {:x [1 2 3 4]
         :y [10 12 9 14]})

(g/plot "data.csv")

Glance tries to do the obvious thing based on the shape of your data:

• A single vector → values vs index
• A map of vectors → inferred x/y or multiple series
• A sequence of maps → columns inferred automatically
• A CSV file (filename or URL) → automatically loaded and visualized

Documentation and Examples

See Glance Documentation or work through the notebook notebooks/index.clj for examples and guidance.

Relationship to Clay, Kindly, Tablecloth, and Noj

Internally, Glance uses Clay to serve content in the browser. It plays well with Kindly (for kinds/annotations) and Tablecloth (for data prep). You do not need to use any of these directly to get value from Glance. They are there when you want more control. In the future Glance might be useful as part of Noj, the collection of Clojure data science libraries.

Status

scicloj.glance is intentionally narrow. Feedback, ideas, and naming discussions are welcome.

The best place to discuss Glance is #noj-dev on Zulip.
