问题更新 - 请参阅下面的编辑部分！
我正在研究Kaggle Dataset about the recent history of the Olympic Games。
我想在内核中添加一些地图，用图表显示全世界金牌得主的分布情况。
我使用了以下不显示输出的代码，请你帮忙吗？
import plotly.graph_objs as go
from plotly.offline import init_notebook_mode,iplot
init_notebook_mode(connected=True)
data = dict(type = 'choropleth',
locations = goldMedals['region'],
locationmode = 'country names',
colorscale = 'Viridis',
reversescale = True,
text= goldMedals['region'],
z = goldMedals['region'],
colorbar = {'title':'gold medals'})
layout = dict(title = 'gold medals',
geo = dict(showframe = False,projection = {'type':'Mercator'})
)
如果您需要查看所有数据，可以查看the complete Kernel on Kaggle。
编辑1：感谢收到的第一个答案，我添加了以下代码来显示地图但我收到了一个valueError
fig = dict(data=data, layout=layout)
iplot(fig)
错误：

The 'data' property is a tuple of trace instances
that may be specified as:
- A list or tuple of trace instances
(e.g. [Scatter(...), Bar(...)])
- A list or tuple of dicts of string/value properties where:
- The 'type' property specifies the trace type
One of: ['area', 'bar', 'box', 'candlestick', 'carpet',
'choropleth', 'cone', 'contour',
'contourcarpet', 'heatmap', 'heatmapgl',
'histogram', 'histogram2d',
'histogram2dcontour', 'mesh3d', 'ohlc',
'parcoords', 'pie', 'pointcloud', 'sankey',
'scatter', 'scatter3d', 'scattercarpet',
'scattergeo', 'scattergl', 'scattermapbox',
'scatterpolar', 'scatterpolargl',
'scatterternary', 'splom', 'streamtube',
'surface', 'table', 'violin']
- All remaining properties are passed to the constructor of
the specified trace type
(e.g. [{'type': 'scatter', ...}, {'type': 'bar, ...}])
答案
要创建输出，您需要使用data和layout变量创建一个数字。然后使用iplot来显示图形。
fig = dict(data=data, layout=layout)
iplot(fig)
根据您尝试制作的地图类型，您可能需要重新格式化data和layout变量。你可以找到不同的地图选项here。
