I'm trying to insert a barchart into my website which has been written in Flask. Here is what my app.py looks like:
from flask import Flask, render_template
app = Flask(__name__)
@app.route("/")
def index():
return render_template('index.html', title="Mainpage")
if __name__=='__main__':
app.run(debug=True)
Here is what my barchart looks like (chart.py):
# -*- coding: utf-8 -*-
import dash
import dash_core_components as dcc
import dash_html_components as html
external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']
app = dash.Dash(__name__, external_stylesheets=external_stylesheets)
app.layout = html.Div(children=[
dcc.Graph(

}
)
])
