In the URL, the value is put using the Javascript. But IMPORTXML cannot retrieve the result after Javascript was run. IMPORTXML retrieves the HTML without running Javascript. I think that your xpath is the result after Javascript was run. By this, they cannot be used. But it seems that the value you expect can be retrieved other xpath.

You need to create a proper installation
I used anaconda to install kivy and I wasn't very thorough with installing the dependencies properly. So I had to create a fresh virtual python installation.

Note: This is for python version 3.5 or higher. Also I am going to have you explicitly state what python installation is going to be creating this environment. To my knowledge, there's no good reason to do this.

Windows

1. (optional) find where python is installed for you.
   Start windows command prompt.
   C:\Users\H>python
import sys, os
os.path.dirname(sys.executable)
   C:\Users\H\AppData\Local\Programs\Python\Python36
   therefore, my python installation is at C:\Users\H\AppData\Local\Programs\Python\Python36\python
2. Prepare a place for your new virtual environment.
   I created a folder called "venvs" in my home directory.
   C:\Users\H\venvs
3. Create new virtual environment. I'll name mine "env1".
   Start windows command prompt.
   if you did step 1
   C:\Users\H>C:\Users\H\AppData\Local\Programs\Python\Python36\python -m venv C:\Users\H\venvs\env1
   if you did not do step 1
   C:\Users\H>python -m venv C:\Users\H\venvs\env1
   
4. Activate the new virtual environment
   C:\Users\H>C:\Users\H\venvs\env1\Scripts\activate
5. Install dependencies
   (env1) C:\Users\H>python -m pip install docutils pygments pypiwin32 kivy_deps.sdl2==0.1.22 kivy_deps.glew==0.1.12
   
6. Install kivy
   (env1) C:\Users\H>python -m pip install kivy==1.11.1
   
7. PyCharm
   If you're using PyCharm, go to File>Settings
   From the settings menu Project>Project Interpreter
   Click the gear>Add
   In the Add Python Interpreter menu select 'Existing environment', then set the interpreter to the location of your new virtual environment.
   Mine was C:\Users\H\venvs\env1\Scripts\python.exe.
   Click Okay. Hit Apply in the settings menu. Once you hit okay, your script should be able to view TIFF files.

In general it's better to map properties to geoms, rather than the top level ggplot object. This allows for finer control.

In this case, map color to the points.
