I recommend VS Code.
Firstly, clone the repository on your local machine.
git clone https://github.com/automatictyping/ARTUR-echarts-data.git
After cloning the repository, go to the working directory and install the dependencies. Then you can start working and the VS code will not show any error messages.
cd ARTUR-echarts-data
npm install
Please see the comments and examples in each *.ts file. I recommend that you start with sunburst_data.ts to get familiar with data.
