Thank you for a great presentation
This video really helped me in my MSc project thanks. That windows key and R shortcut for the path is soooooo useful. Keep up the good work Thanks
I am super glad it was useful!
This was really well summed up, thanks
ur welcome
Thank you, your explanation was complete but straightforward c:
Glad it helped!
Explicitly explained!!!
Sir, can you please advise what to write at the below line of code, if i have all geo-coordinates of one courty (i.e. India)? I tried the below code but it's not working somehow.
axis = world_data[world_data.continent=='india']
Your explanations are very useful.
Glad you think so!
Great video
thanks man!
at 8:44: what if we wanted each city in a different color? for example, if the dataframe had a column with city population, and we wanted to have cities with bigger populations in a darker color, and cities with less population in brighter color? thanks, great video
I've not tried it myself but in more standard matplotlib plots you can add another column which has the color for each row and pass that entire column into the color argument.
Hey !! awesome video!! thanks a lot bro !! I am just wondering is there any way for us to change the map projection of the final choropleth map?
hello tom. sorry this is coming very late. yes you can change the projection to "orthographic" etc using plotly
Does this work on pycharm, with the modules installed ?? I am having trouble with this on pycharm right now
thank uuu!
ur welcome
Thanks!
No problem!
Hi! I could not find the csv file. where is it? Thanks!
im not getting the desired image, like the points are plotted at one corner and the country image is plotted on other corner, how can i solve this and get them into position, someone please help me.
Thank you
You're welcome
Hi, thank you for this intersting vedeo. Where can I find a geojson file for morocco including sahara? Thank a lot for your help
hello Nadia. you can google search for free geojson files. there are quite free to get.
Can this be applied too on google colab
Instead of country map can it be applied to states map and local government area maps?
sure. it can. all you need are filters to point to your data
how would I set the continent to display a map of the United Kingdom? (UK)
you could use a list to manually load the longitudes and latitudes. or use the country code in the api
Is there a way to contact you
Can we draw a line connecting those dots?
yes we can. the lines can even have color, thickness etc
I could not isntall geopandas.
I tried to import geopandas but I couldn't, and this error has appeared
ModuleNotFoundError: No module named 'geopandas'
lol my error is no module named "plotly"
hey I found out that it's related to your python environment. if you are using jupyter notebook, you could try the code "pip list". it will list all installed packages. if geopandas is not installed in this environment, just get it. I bet it will sort your issue.
@@tomzhang7152 I’ll try this! Thanks for help
ModuleNotFoundError: No module named 'matplotlib.pylplot'
What should I do to fix this?
hello. you can try typing "pip install matplot lib" in your command line. also installing pandas will usually come with the matplot lib library installed
Thanks I fixed.
