3D graph request

1. A concise explanation of the problem you're experiencing.

I'm trying to install Cesium 1.59, but installing just won't work.
I downloaded the Cesium software package, I downloaded Node.js, but I keep getting errors.

2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.

When I gave the command 'npm install' I got the error "ENOENT: no such file or directory", while I went to the root directory.
When I gave the command 'node server.js' I got the error "ERROR: Cannot find module 'C:\Users\maptable 2015-11>node server.js
internal/modules/cjs/loader.js:638
throw err;

When I gave the command 'npm install' again, I got the error "ENOENT: no such file or directory, open C:/package.json" after that it says: "EPERM: operation not permitted, open C:/package-lock.json1879709702". But I can't find that file anwyhere.
After that it says: "ENOENT: no such file or directory, open C:/package.json".

Then I tried an other command: "C:/>npm install cesium" but I got the same errors again: "ENOENT: no such file or directory, open C:/package.json" after that it says: "EPERM: operation not permitted, open C:/package-lock.json1879709702". But I can't find that file anwyhere.
After that it says: "ENOENT: no such file or directory, open C:/package.json".

I watched several youtube videos, but everything what works there, doesn't work on this PC. There are so many videos on USING Cesium, but only few (one?) on INSTALLING Cesium. Why isn't there a manual I can download? Would make it a lot easier... Anyway, I'm struggling for 4 hours now and can't figure out how to make Cesium actually RUN on this computer. I am willing to learn, but time is runnning out now actually. If this is only the start, I'm not confident I'll get around in Cesium very quickly. It seems very unfriendly to me.

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
Because I'm working on a 3D map for a school project, I would kindly request someone who actually CAN ACCESS Cesium, to import either the attached KML or GPX file.
We did a balloon flight and need to draw a 3D map for that.

If someone could do that for me, download/export it and post it here, I would be very grateful!

And again: I am willing to learn, but this just takes too much time right now to do every step myself.

4. The Cesium version you're using, your operating system and browser.

Cesium Version: Cesium 1.59
Operating System: Windows 10 Home, Version 1803
Browser: Google Chrome Version 75.0.3770.100 (Official build) (64-bits)

Have you seen the getting started tutorial?

https://cesium.com/docs/tutorials/getting-started/

It describes how to get started without needing to manually set up CesiumJSā€™s development environment. That should be a much easier way to get started.

Best of luck!

Thanks a lot Omar, that was hidden well... haha
I managed to finish the steps mentioned in the Getting Started manual.
Now the library is closing so I can't import/upload the data into Cesium anymore :frowning:
