A visualization system build on Node.js for Twitter trends propagation and topic geotagging.
- ejs: We use ejs as the default template engine. It's simple.
- express: The lightweight web framework we use.
- mongodb: All the tweets raw data are stored in MongoDB. Here we choose node-mongodb-native as the connect module. Since the raw json format of one tweet is too complex, we avoid using mongoose to model it.
- socket.io: For passing some import data between client and server.
- d3.js
- Leaflet
- Leaflet-heat
- Bootstrap 3.x
