RSATree: Distribution-Aware Data Representation of Large-Scale Tabular Datasets for Flexible Visual Query

RSATree is a novel data representation, which supports flexible approximate query of large-scale tabular datasets and interactive interface in different scenarios. The project is developed by Visual Analytics Group from State Key Lab of CAD&CG, Zhejiang University, China.

Build and Run

We are open two demos about our algorithm.

Our coding environment is ubuntu 18.04 with 32GB RAM, 500GB SSD

C++ version is gcc 7.4.0, node version is v10.16.0, cmake version is 3.10.2

Construct the data structure

First you need to install a library for reading json files

I uses the library from https://github.com/nlohmann/json.git

git clone https://github.com/nlohmann/json.git
cd json
mkdir build
cd build
cmake ..
make -j8
sudo make install

there is a template about how to builld BRIGHTKITE datasets using C++

I have prepared a smaller binary file of BRIGHTKITE in folder ./construct/data

cd construct
mkdir result
mkdir build
bash build.sh
./solveBrightkiteDays
cp result/* ../backend/data/BRIGHTKITE

Install libraries using npm

cd frontend
npm install
npm audit fix 
cd ../backend
npm install
npm audit fix

Run the server

# start frontend 
cd frontend
npm run debug


# then start a new terminal then start backend 
cd backend
npm run start

you will see the website on http://localhost:8081/
