英文:
Vega lite spec Displaying an empty graph inspite of being provided with data in the spec
问题
Vega Lite规范显示一个空的图表，尽管规范中提供了数据。链接包含了正确的规范和空图表。我需要帮助找出错误在哪里。我尝试在Streamlit应用程序的一部分中显示此图表。我没有看到任何JavaScript或Python错误，只有一个空图表。
英文:
Vega lite spec showing an empty graph without any data points inspite of data being provided inside the spec. The link has the appropriate spec and empty graph. I need help in figuring out what the error is. I am trying to display this graph as part of a streamlit app. I am unable to see any javascript or python errors. Just an empty graph.
