Autark: A Serverless Toolkit for Prototyping Urban Visual Analytics Systems

2026-04-22

AI Summary

This work addresses the complexity of developing urban visual analysis systems and the lack of lightweight, unified tools that support rapid prototyping and reproducibility. To this end, we propose Autark—the first serverless toolkit tailored for urban visual analysis—which efficiently translates design intent into shareable systems through a self-contained architecture and domain-aware abstractions. Autark innovatively integrates serverless computing with structured APIs to enable spatial data management, analytical processing, visualization, and large language model (LLM)-assisted programming, substantially enhancing code reliability and development efficiency. Experimental results demonstrate that Autark enables the construction of diverse urban visual analysis prototypes within hours, offering significant advantages in development speed, system reproducibility, and effectiveness of LLM-augmented programming.

Abstract

The development of visual analytics (VA) systems has traditionally been a labor-intensive process, balancing design methodologies with complex software engineering practices. In domain-specific fields like urban VA, this challenge is amplified by heterogeneous data streams and a reliance on complex, multi-service architectures that hinder fast development, deployment, and reproducibility. Despite the richness of the urban VA literature, the field lacks a consolidated toolkit that encapsulates the core components of these systems, such as spatial data management, analytical processing, and visualization, into a unified, lightweight framework. In this paper, we introduce Autark, a serverless toolkit designed for the rapid prototyping of urban VA systems. Autark provides domain-aware abstractions through a self-contained architecture, enabling researchers to transition from design intention to deployed, shareable systems within hours. Furthermore, Autark's structured, tightly scoped interfaces make it well-suited for AI-assisted coding workflows, where LLMs produce more reliable code when composing from well-defined abstractions rather than generating complex solutions from scratch. Our contributions are: (1) the Autark toolkit, a serverless architecture for rapid prototyping of urban VA; (2) a comparative study of LLM coding effectiveness with and without Autark; and (3) a series of usage scenarios demonstrating its capability to streamline the creation of robust, shareable urban VA prototypes. Autark is available at https://autarkjs.org/.
