2050 website design, graph part

By 古思为

设计需求 via 庄表伟

简单介绍一下我的思路。在2050，最重要的就是人与人之间产生的各种关系，我是被谁“interface”来的，我又“interface”了哪些人。我发起了一个，有哪些因此被吸引而来（有些人是来帮忙，有些人只是来参加活动），我在2050的聚会中，与谁聊得特别开心，后来就follow了TA，进一步关注TA的一举一动，等等。

在一个人的个人页面上，我们会在右侧，先简单展示他的“上下游”关系，点击更多，可以把各种关系都展示出来，越是与他有N种关系的人，就会离他越近

run Louvain in nebula-algorithm

Here is an example that I performed a Louvain algorithm, it's basically what I had done in this post: https://siwei.io/nebula-livejournal/

Nebula Console:

CREATE SPACE louvain (partition_num=15, replica_factor=1, vid_type=FIXED_STRING(256)) comment="louvain test";

create tag user() comment = 'user';

create edge relation(weight int)  COMMENT = 'user relation';
