Evaluator

spytial.evaluate() renders a lightweight view of the serialized data instance. Use this function to check how Python objects translate before layout work begins.

Basic usage

import spytial

spytial.evaluate({"total": 3, "items": [1, 2, 3]})

When it helps

The evaluator helps in these cases:

• a custom class does not relationalize as expected
• a selector does not match as expected
• a custom relationalizer is being written, and its emitted atoms and relations need inspection

Display methods

spytial.evaluate(data, method="browser")  # open a new tab
spytial.evaluate(data, method="file")     # save as cnd_evaluator.html
spytial.evaluate(data, method="inline")   # force notebook output

Size options

spytial.evaluate(data, width=800, height=300)

Using annotated types

from typing import Dict, List
from spytial import AnnotatedType, InferredEdge, Orientation

Graph = AnnotatedType(
    Dict[int, List[int]],
    InferredEdge(name="edge", selector="values"),
    Orientation(selector="values", directions=["right"]),
)

spytial.evaluate({0: [1, 2], 1: [3]}, as_type=Graph)
