pyd2lang-native

Native Python bindings for the d2lang diagram compiler. Compile D2 diagram code to SVG directly from Python without requiring the d2 CLI.

Includes two built-in component libraries with ADI brand themes:

  • ADI — 64 analog/mixed-signal shapes for signal chain diagrams

  • SW — 32 software/AI shapes for architecture and agent pipeline diagrams

Installation

pip install pyd2lang-native

Quick Start

import d2

svg = d2.compile("x -> y")

With ADI components:

import d2

code = """
direction: right
adc1: AD7606 { class: adc }
filt1: LTC1560 { class: filter-lp }
amp1: LT6230 { class: amplifier }

amp1 -> filt1: Analog { class: adi-signal-analog }
filt1 -> adc1: Filtered { class: adi-signal-analog }
"""

svg = d2.compile(code, library="adi")

With SW components:

import d2

code = """
agent: Auditor { class: sw-agent }
model: Claude { class: sw-model }
tool: Search { class: sw-tool }
doc: Seed { class: sw-document }

doc -> agent { class: sw-flow-data }
agent -> tool -> model { class: sw-flow }
model -> agent { class: sw-flow-feedback }
"""

svg = d2.compile(code, library="sw")
