[GitHub] [age] im-aditya30 commented on issue #745: Research about similarities and differences in NetworkX and AGE

   NetworkX is a python package, which focuses on the study of complex networks 
using graphs and is mainly used for analysis. Its nodes can be any object that 
is hashable, meaning that its value never changes. These can be text strings, 
images, XML objects, entire graphs, and customized nodes. 
   
   AGE on the other hand uses query written in SQL and Cypher and provides 
graph database functionality, which means to provide graph data processing and 
analytics capability to all relational databases. It also provides access to 
graph query modeling within the existing relational database.

   @dehowef For safe parameter handling, the solution I landed on is built on 
PostgresNIO's string interpolation. This code:
   ```swift
   let params: Dictionary = ["newName": "Little'Bobby'Tables"]
   let paramsWrapper: AGValueWrapper = AGValueWrapper.init(value: params)
   let agRows = try await connection.execCypher(
"SELECT * FROM cypher('test_graph_1', $$ CREATE (v:Person {name: 
$newName}) RETURN v $$, \( paramsWrapper )) as (v agtype);",
logger: logger)
   ```
   will send the following query to Postgres:
   ```sql
   SELECT * FROM cypher('test_graph_1', $$ CREATE (v:Person {name: $newName}) 
RETURN v $$, $1) as (v agtype);
   ```
   with the `$1` parameter being a jsonb encoding of that Dictionary. Let me 
know if you see any concerns with that approach.

   @Munmud Apache AGE doesn't support external links that we have no control 
over. This specific link was brought to our attention a few days ago and we are 
removing references to PYPI until it is under our control.

   This is happening because the project decription at pypi.org is not correct.
