Containarium vs flint-chart

Containarium: Containarium is an open-source, self-hostable, agent-native sandbox that provides persistent, isolated, and real Linux environments for AI agents to build, install, deploy, and verify their work. It runs as a single-host platform using LXC containers, exposing its administration via MCP and CLI, and includes an in-container MCP server for direct shell execution and file operations.; flint-chart: Flint is a visualization intermediate language designed for AI agents to generate high-quality charts from concise, human-editable specifications. It compiles these specs into native Vega-Lite, ECharts, or Chart.js formats, abstracting away complex configuration details like scales and layouts.
