folium

This question already has answers here : How to serve static files in Flask (16 answers) So I am using this cool plugin called Folium which creates maps. The map gets created as a .html and every time you update the map it regenerates the html. So in order to display the map and my navbar and other stuff on the same page I think I would need to put map.html inside an iframe cage where it can refresh itself at will. The map gets created thus: map1 = folium.Map(location=[45.5, -73.61], width="100%", height="100%") map1.save('./maps/map.html') And I have tried iframeing it thus: <iframe src="

I'm trying to plot radar data in folium, and I'm almost there. I followed this example ( Contour plot data (lat,lon,value) within boundaries and export GeoJSON ) to get my data into a GeoJson format. nb_class = 20 collec_poly = plt.contourf(lons,lats,np.array(poshdata), nb_class,alpha=0.5) gdf = collec_to_gdf(collec_poly) # From link above gdf.to_json() colors = [p.get_facecolor().tolist()[0] for p in collec_poly.collections] gdf['RGBA'] = colors gdf This outputs two columns: geometry and RGBA. RGBA geometry 0 [0.0, 0.0, 0.713903743316, 1.0] (POLYGON ((-71.57032079644679 42.2775236331535... 1

I want to insert follium map into the jinja template. run.py from flask import Flask, render_template app = Flask(__name__) @app.route('/') def index(): start_coords = (46.9540700, 142.7360300) folium_map = folium.Map(location=start_coords, zoom_start=14) folium_map.save() return render_template('index.html', folium_map=folium_map) if __name__ == '__main__': app.run(debug=True) template/index.html - jinja template for Flask {% extends "layout.html" %} {% block title %}Test{% endblock %} {% block head %} {{ super() }} {% endblock %} {% block body %} **<div><!--Folium map here-->{{ folium_map }}

I'm working on producing a series of maps for an animated presentation using Folium and my code (when plotting over 100 circles) always ends in a blank map. If I decrease the number of circles to 100 or below, it works perfectly. Is this a folium limitation or something I can change on my local machine with Java or Browser settings? I'm using python in jupyter notebook in chrome on Ubuntu. merged_hourly is a pandas df with nyc foottraffic data for specific stations, lat, long, etc. Exported Dataframe is located here as a spreadsheet: https://docs.google.com/spreadsheets/d/1XroOBPUWOqZsy

I am not getting any color variation in my output map even after the choropleth is linked with the geo_data and the data frame is linked with data parameter in the choropleth method. I have provided the "key_on" parameter rightly and the "columns" parameter rightly. I have removed all the NULL values from the Dataframe. import pandas as pd from pandas import read_csv import folium import os import webbrowser crimes = read_csv('Dataframe.csv',error_bad_lines=False) vis = os.path.join('Community_Areas.geojson') m = folium.Map(location = [41.878113, -87.629799], zoom_start = 10, tiles =

I tried to create a Map using folium library in python3. It work's fine until i add a Marker to the map. On adding Marker the output results in just a blank HTML page. import folium map = folium.Map(location=[20.59,78.96], tiles = "Mapbox Bright") folium.Marker([26.80,80.76],popup="Hey, It's Moradabad").add_to(map) map.save("mapOutput.html") @MCO is absolutely correct. I like to leverage html.escape() to handle the problem characters like so import folium import html map = folium.Map(location=[20.59,78.96], tiles = "Mapbox Bright") folium.Marker([26.80,80.76],popup=html.escape("Hey, It's

I am trying to display the following geojson file in a folium map in Python but it just shows an empty map with none of the data. Here are the steps I have tried: I tried using the python code below but nothing shows up. I tried other geojson files in the github repository below using the same code and the data show up without any issue, so it looks like my python code is fine I opened the "census_tracts_2010.geojson" file in github and Mapshaper , the data showed up perfectly without any issue, so it doesn't look like the geojson file is corrupted Could anyone please let me know how I can fix

I'm trying to do a choropleth using folium which offers a great link between GeoJSON, Pandas and leaflet. GeoJSON format is like below : { "type":"FeatureCollection", "features":[ { "type":"Feature", "geometry": { "type":"Polygon", "coordinates":[[[-1.6704591323124895,49.62681486270549], ..... { "insee":"50173", "nom":"Équeurdreville-Hainneville", "wikipedia":"fr:Équeurdreville-Hainneville", "surf_m2":12940306}}, Pandas DataFrame : postal_count.head(5) Out[98]: Code_commune_INSEE CP_count 0 75120 723 1 75115 698 2 75112 671 3 75118 627 4 75111 622 "Code_communes_INSEE" corresponds to the
