## What it is
Blast Radius is a tool that renders interactive visualizations of Terraform dependency graphs using Graphviz layouts enhanced with d3.js. It is installed via pip and serves the visualization in a local browser, with Docker support available.

## Use cases
- visualize terraform dependency graph
- document my infrastructure as code
- understand relationships between terraform resources
- generate diagrams from terraform state
- learn terraform providers through example graphs
- evaluate impact of terraform changes

## When to choose
- you use Terraform and want interactive, searchable dependency graphs
- you need diagrams to document infrastructure for a team
- you want a quick pip or Docker install with a local web UI

## When to avoid
- you use infrastructure tools other than Terraform
- you need headless CI-generated static images rather than an interactive browser view
- you need actively developed features or recent Terraform compatibility guarantees

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: data-visualization, developer-tools, documentation, cli
- domain: infrastructure-as-code, developer-tools, cloud-computing
- platform: python, cross-platform, cli, browser
- tags: terraform, graphviz, d3js, dependency-graph, infrastructure-diagrams, interactive-visualization, devops, docker
