These code snippets demonstrate how to add rows to a dataframe or a chart after displaying them using Streamlit:
For a dataframe
element = st.dataframe(df1)
displays the initial dataframe df1.
element.add_rows(df2)
adds rows from another dataframe df2 to the displayed dataframe.
For a chart
element = st.line_chart(df1)
displays the initial line chart using data from df1.
element.add_rows(df2)
adds data from another dataframe df2 to the displayed chart.
