如何使用Dash绘制CSV文件中的数据

import dash
import dash_core_components as dcc
import dash_html_components as html
import pandas as pd

df = pd.read_csv('your_file.csv')

app = dash.Dash(__name__)

app.layout = html.Div(children=[
    html.H1(children='CSV 数据可视化'),
    dcc.Graph(
        id='example-graph',
        figure={
            'data': [
                {'x': df['x_column'], 'y': df['y_column'], 'type': 'bar', 'name': '数据'},
            ],
            'layout': {
                'title': 'CSV 数据图表'
            }
        }
    )
])

if __name__ == '__main__':
    app.run_server(debug=True)
