+# GCP Architecture Visualizer
+
+This tool serves a single, simple purpose: visualizing a user's GCP architecture and environment, so that they have a dynamic and simple-to-use way to view their world in GCP.
+
+It does this by:
+
+* Ingesting a strictly-formatted CSV input file, which is generally output from a [Forseti Security](http://forsetisecurity.org) Inventory scan.
+* Dynamically building the parent->child tree of inventory resources in GCP.
+* Drawing an interactive tree structure using D3.js, containing useful GCP info and per-resource icons.
+
+
+## Usage
+
+The tool has been tested with [Forseti Security](http://forsetisecurity.org) 2.0, and can be used to draw out any CSV input (currently stored in gcp-data.csv) that conforms to the following schema:
+
+```
+id, resource_type, category, resource_id, parent_id, resource_name
+```
+
+CSV generation currently performed using Google Cloud SQL export from Forseti Security Inventory tables, using the query below:
+
+```
+SELECT id, resource_type, category, resource_id, parent_id, IFNULL(resource_data->>'$.displayName', '') as resource_data_displayname, IFNULL(resource_data->>'$.name', '') as resource_data_name FROM gcp_inventory WHERE inventory_index_id = (SELECT id FROM inventory_index ORDER BY completed_at_datetime DESC LIMIT 1) AND (category='resource') AND  (resource_type='organization' OR resource_type='project' OR resource_type='folder' OR resource_type='appengine_app' OR resource_type='kubernetes_cluster' OR resource_type='cloudsqlinstance');
+```
+
+Other useful queries:
+
+__Get id of latest inventory scan (timestamp):__
+```
+SELECT id FROM inventory_index ORDER BY completed_at_datetime DESC LIMIT 1;
+```
+
+__Check schema of gcp_inventory table (in case schema changes, and query needs to be updated):__
+```
+Describe forseti_security.gcp_inventory;
+```
+
+## Examples
