要實(shí)現(xiàn)互動(dòng)式地圖可視化,可以使用Matplotlib的Basemap工具包結(jié)合mplleaflet庫。具體步驟如下:
- 首先安裝Basemap和mplleaflet庫:
pip install basemap
pip install mplleaflet
- 導(dǎo)入必要的庫:
from mpl_toolkits.basemap import Basemap
import matplotlib.pyplot as plt
import mplleaflet
- 創(chuàng)建Basemap對象并繪制地圖:
m = Basemap(projection='mill',llcrnrlat=-90,urcrnrlat=90,llcrnrlon=-180,urcrnrlon=180,resolution='c')
m.drawcoastlines()
m.drawcountries()
m.drawmapboundary()
- 添加數(shù)據(jù)點(diǎn)到地圖上:
lons = [longitude1, longitude2, ...]
lats = [latitude1, latitude2, ...]
x, y = m(lons, lats)
m.scatter(x, y, color='red', marker='o', zorder=5)
- 顯示地圖:
plt.title('Interactive Map Visualization')
mplleaflet.display()
通過這些步驟,即可實(shí)現(xiàn)基于Matplotlib的互動(dòng)式地圖可視化。
