Regarding projection system(crs) for graph generation

[rockbusteriitk]

Hi,

I tried theEPSG:3857 Projection.

"from geograph import GeoGraph
data= r'D:\Geograph\lulc_test\lulc_2021.tif'
graph = GeoGraph(data,crs="EPSG:3857")"

and

"from geograph.visualisation.geoviewer import GeoGraphViewer
viewer = GeoGraphViewer()
viewer.add_graph(graph, name='my_graph')
#viewer.enable_graph_controls()
viewer"

and I received the error:
"AttributeError Traceback (most recent call last)
Cell In[5], line 3
1 from geograph.visualisation.geoviewer import GeoGraphViewer
2 viewer = GeoGraphViewer()
----> 3 viewer.add_graph(graph, name='my_graph')
4 #viewer.enable_graph_controls()
5 viewer

--> 622 val = getattr(super(), mtd)(*args, **kwargs)
623 if type(val) == Series:
624 val.class = GeoSeries

AttributeError: 'super' object has no attribute 'append"

What might be the problem and is there a wayaround?

I'm also getting this error.

Looks like it's related to the append function being deprecated in pandas.

Similar issue: https://stackoverflow.com/questions/75956209/error-dataframe-object-has-no-attribute-append

Can get around it by updating functions similar to this:
