霍罗珀斯图不着色国家？

Question

I asked a question yesteday, but i guess it was a bit too much code or unclear, so i've deleted it and will try to make my question more clear.

I have a dataframe (df) with all the countries in the world, it looks like this :

Country CountryCode Population
0   Afghanistan AF  30206627.0
1   Åland Islands   AX  NaN
2   Albania AL  2881160.0
3   Algeria DZ  37812804.0
4   American Samoa  AS  NaN

My choropleth code looks like this:

data = dict(type = 'choropleth', 
           locations = df['CountryCode'],
           z = df['Population'],
           text = df['Country'],
           colorbar = dict(title = 'Population'))

layout = dict(title = '2013 global Population', 
             geo = dict(showframe = False,
                       projection = {'type': 'stereographic'}))

choromap = go.Figure(data = [data], layout = layout)

plot(choromap)

When i run my code i get the following result:

As you can see my population bar is colored correctly, and it takes the correct population values from the dataframe and puts them on the population bar. So what am i doing wrong here, since i just gives me a blank map, instead of coloring the different countries?

Thank you in advance Best regards .

我发现，在将我的弦谱图导出到Ploty之后，问题确实是我使用的是ISO-2而不是ISO-3，所以我想我必须找到一种转换代码的方法。
