Make it extremely useful, yet smooth, elegant and easy.

Phase 0

[x] Config/SessionPoolConfig should be possible to be omitted, enable one-liner to access and query, via https://github.com/vesoft-inc/nebula-python/pull/323/files#diff-da4517b6eb66b1d80bb6975a7200825a2e896c7b97f4fe87943cc361a211da32 and https://github.com/vesoft-inc/nebula-python/pull/323/files#diff-cb5002afe3dfed88eacf95684dd290ec79d3b7801a53fa634fcc09992555c86f
[x] Getting Started docs should be straightforward, via #323
[x] Should be possible to render/vis any result with ease(like render FIND PATH/MATCH path/GET SUBGRAPH result is HARD), via #323
[x] Should be easy to have results as pandas dataframe, via #323
[x] Handling of reconnection/timeout etc., via #306
[x] modern package management, via PDM

[ ] Should be easy to prepare query param, instead of handling raw types to be passed, https://github.com/vesoft-inc/nebula-python/issues/273
[ ] fully typed
[x] ETL from CSV/Pandas DF https://github.com/vesoft-inc/nebula-python/issues/261
[ ] Schema reconcile: interface for performing DDL in a block and idempotent way like Apply_XXX by @haoxins in go client/operator #344
[ ] interface of DML with client-side transaction(optionally)
[ ] Export to network X, iGraph, DGL, PyG in one line
[ ] Render portable html files from resultSet
[ ] Implement same hash func as it was in NebulaGraph, ref: https://gist.github.com/wey-gu/5543c33987c0a5e8f7474b9b80cd36aa
[ ] Client Performance: cython #327 or WIR #319
[ ] GraphAR export/import https://github.com/apache/incubator-graphar
[ ] address scheme like nebula://localhost:9669 support
