【531】folium 实现地图可视化（热力图）

瓦片修改：

点线面显示举例

　　Polygon 通过 weight 调整边界线的宽度

import folium
# 用于 MarkerCluster
import folium.plugins 
 
# 加载高德地图瓦片
m=folium.Map(location=[40.00727, 116.486635],
               zoom_start=17,
               tiles='http://webst04.is.autonavi.com/appmaptile?style=7&x={x}&y={y}&z={z}',
               attr='default')
 
# 单点，直接加入坐标即可
folium.Marker(
    [40.00777, 116.486635],
    popup=folium.Popup('望京科创园',max_width=1000),
    tooltip='click here').add_to(m)
 
# 多边形，需要所有的点，可以填充颜色
folium.Polygon(
    [[40.00777, 116.485635],
     [40.00697, 116.488035],
     [40.00877, 116.487635]],
    color='red',
    fill_color='red',
    fillOpacity=0.5).add_to(m) 
 
# 折线，需要所有的点，只有颜色
folium.PolyLine(
    [[40.00677, 116.485635],
     [40.00597, 116.488035],
     [40.00777, 116.487635]],
    color='green').add_to(m) 
 
# 圆圈显示
folium.Circle(
    [40.00677, 116.485635],
    50,
    color='purple',
    fill_color='purple',
    fillOpacity='purple').add_to(m) 
 
folium.CircleMarker(
    location=[40.00597, 116.488035],
    radius=20,
    popup="Laurelhurst Park",
    color="#3186cc",
    fill=True,
    fill_color="#3186cc",
).add_to(m)
 
# 显示点集
folium.plugins.MarkerCluster(
    locations=[[40.00677, 116.485635],
               [40.00597, 116.488035],
               [40.00777, 116.487635]],).add_to(m)

Init signature:
folium.Marker(
    location=None,
    popup=None,
    tooltip=None,
    icon=None,
    draggable=False,
    **kwargs,
)
Docstring:     
Create a simple stock Leaflet marker on the map, with optional
popup text or Vincent visualization.
 
Parameters
----------
location: tuple or list
    Latitude and Longitude of Marker (Northing, Easting)
popup: string or folium.Popup, default None
    Label for the Marker; either an escaped HTML string to initialize
    folium.Popup or a folium.Popup instance.
tooltip: str or folium.Tooltip, default None
    Display a text when hovering over the object.
icon: Icon plugin
    the Icon plugin to use to render the marker.
draggable: bool, default False
    Set to True to be able to drag the marker around the map.
 
 
Init signature: folium.Polygon(locations, popup=None, tooltip=None, **kwargs)
Docstring:     
Draw polygon overlays on a map.
 
See :func:`folium.vector_layers.path_options` for the `Path` options.
 
Parameters
----------
locations: list of points (latitude, longitude)
    Latitude and Longitude of line (Northing, Easting)
popup: string or folium.Popup, default None
    Input text or visualization for object displayed when clicking.
tooltip: str or folium.Tooltip, default None
    Display a text when hovering over the object.
**kwargs
    Other valid (possibly inherited) options. See:
    https://leafletjs.com/reference-1.6.0.html#polygon
 
 
Init signature: folium.PolyLine(locations, popup=None, tooltip=None, **kwargs)
Docstring:

Parameters
----------
locations: list of points (latitude, longitude)

tooltip: str or folium.Tooltip, default None
    Display a text when hovering over the object.
smooth_factor: float, default 1.0
    How much to simplify the polyline on each zoom level.
    More means better performance and smoother look,
    and less means more accurate representation.
no_clip: Bool, default False
    Disable polyline clipping.
**kwargs
    Other valid (possibly inherited) options. See:
    https://leafletjs.com/reference-1.6.0.html#polyline
