要实现互动式地图可视化,可以使用Matplotlib的Basemap工具包结合mplleaflet库。具体步骤如下:
- 首先安装Basemap和mplleaflet库:
pip install basemap pip install mplleaflet
- 导入必要的库:
from mpl_toolkits.basemap import Basemap import matplotlib.pyplot as plt import mplleaflet
- 创建Basemap对象并绘制地图:
m = Basemap(projection='mill',llcrnrlat=-90,urcrnrlat=90,llcrnrlon=-180,urcrnrlon=180,resolution='c') m.drawcoastlines() m.drawcountries() m.drawmapboundary()
- 添加数据点到地图上:
lons = [longitude1, longitude2, ...] lats = [latitude1, latitude2, ...] x, y = m(lons, lats) m.scatter(x, y, color='red', marker='o', zorder=5)
- 显示地图:
plt.title('Interactive Map Visualization') mplleaflet.display()
通过这些步骤,即可实现基于Matplotlib的互动式地图可视化。
