@prk2331 I just solved this! Please close if it is fixed now.

The issue is some dependency has a corrupted package.json file. I fixed that dependency with commit https://github.com/iVis-at-Bilkent/cytoscape.js-chola/commit/95e010ecd1a86af0ab0caf5087893e6f6fc5c9aa Also since I don't use those dependencies I also removed them.

Check now. I checked with "npm 6.14.14" and "node v16.13.1". npm i and then npm run start works fine. Thank you.

@canbax Thanks for your response Really appreciated! Yaa I checked its working now with node JS Backend, Can you please provide me quick guidance,
I connect it with tigerGraph, But I am unable to get the SVG icons on the nodes, which is in my graph schema, can you please provide some guidance on this ?

[canbax]

Styles and icons in the tiger graph are totally unrelated. Here we make visualization with cytoscape.js So you should give cytoscape.js styles

For a sample, you can load https://github.com/canbax/davraz/blob/master/src/assets/cytoscape.js-style/covid19.json with "File>Load Graph Style" and then you can load a graph compatible with this style. You can load a graph such as https://github.com/canbax/davraz/blob/master/src/assets/sample_data/covid-19-sample-data.json with "File>Load"

@canbax yes I checked the visualization by (Loading Covid 19 data and Covid 19 syling) this is working perfect I also check the table format , and Layout algorithms (circle , Grid, fcose, euler, grid etc). I checked with TigerGraph connection as well
when I click on the RUN Installed Queries and pass params accordingly which are required, then the nodes are also coming well in Grey color I explore their neighbor's (Neighbors are also coming in grey color) , But here I am trying to implement (that there is any way to give the different colors to the nodes like for example All profiles nodes are of red color :-(liked Products)- All Products are in Pink and so on.. in that way) just for differentiate the (vertices/nodes) in the large Schema Can you please guide me for that, this will be really helpful.

[canbax]

You should write your own styles. You can inspect the covid 19 style file and read the docs about cytoscape.js styles

[prk2331]

@canbax thanks I understood the whole concept we will be able to give the Style in Json file according to the rendered Nodes and load the Json file via Load Graph style tab
But here I am facing an issue that when we load the data from Sample data like COVID data which is given in the sample folder then clear the rendered graph, after that when we run our Installed GSQL queries nodes are not coming so this happens only when we load Sample data and then we clear and run our installed query can you please provide some help!

[canbax]

You should also clear the styles. The data and styles are 2 different things. The data and styles should also be compatible. If you load a data, you should use compatible styles.

@canbax Thank you so much, I got it
