使用Python pygal模块绘制世界地图示例

Linux系统环境：Ubuntu 18.04 LTS

Python版本：Python 3.6.7

首先安装：pygal_maps_world

linuxidc@linuxidc:~/linuxidc.com$ pip3 install pygal_maps_world -i https://pypi.douban.com/simple/

此时可以访问pygal.maps.world模块，并指定代码绘制国家

示例代码：

import pygal

from pygal_maps_world.i18n import COUNTRIES

def word_country_map():

"""世界各国"""

wm = pygal.maps.world.World()

wm.force_uri_protocol = 'http'

wm.title = "世界地图"

for code,name in COUNTRIES.items():

wm.add(name,code)

wm.add('Yemen',{'ye':'Yemem'})

wm.render_to_file('linuxidc.svg')

def one_country_map():

wm = pygal.maps.world.World()

wm.force_uri_protocol = 'http'

wm.title = '世界地图(一国)'

wm.add('North America', ['ca', 'mx', 'us'])

wm.render_to_file('linuxidc.com.svg')

if __name__ == '__main__':

wm = pygal.maps.world.World()

wm.title = 'North,Central,and South America'

wm.add('North America', ['ca', 'mx', 'us'])

wm.add('Central America', ['bz', 'cr', 'gt', 'hn', 'ni', 'pa', 'sv'])

wm.add('South America', ['ar', 'bo', 'br', 'cl', 'co', 'ec', 'gf',

'gy', 'pe', 'py', 'sr', 'uy', 've'])

wm.render_to_file('www.linuxidc.com.svg')

word_country_map()

one_country_map()

绘制图如下：

Countries

import pygal.maps.world

worldmap_chart = pygal.maps.world.World()

worldmap_chart.title = 'Some countries'

worldmap_chart.add('F countries', ['fr', 'fi'])

worldmap_chart.add('M countries', ['ma', 'mc', 'md', 'me', 'mg',

'mk', 'ml', 'mm', 'mn', 'mo',

'mr', 'mt', 'mu', 'mv', 'mw',

'mx', 'my', 'mz'])

worldmap_chart.add('U countries', ['ua', 'ug', 'us', 'uy', 'uz'])

worldmap_chart.render_to_file('www.linuxidc.com.svg')

如下图：

指定某个国家的值：

import pygal.maps.world

worldmap_chart = pygal.maps.world.World()

worldmap_chart.title = 'Minimum deaths by capital punishement (source: Amnesty International)'

worldmap_chart.add('In 2012', {

'af': 14,

'bd': 1,

'by': 3,

'cn': 1000,

'gm': 9,

'in': 1,

'ir': 314,

'iq': 129,

'jp': 7,

'kp': 6,

'pk': 1,

'ps': 6,

'sa': 79,

'so': 6,

'sd': 5,

'tw': 6,

'ae': 1,

'us': 43,

'ye': 28

})

worldmap_chart.render_to_file('www.linuxidc.com.svg')

如下图：

Continents

获取洲地图

import pygal.maps.world

supra = pygal.maps.world.SupranationalWorld()

supra.add('Asia', [('asia', 1)])

supra.add('Europe', [('europe', 1)])

supra.add('Africa', [('africa', 1)])

supra.add('North america', [('north_america', 1)])

supra.add('South america', [('south_america', 1)])

supra.add('Oceania', [('oceania', 1)])

supra.add('Antartica', [('antartica', 1)])

supra.render_to_file('www.linuxidc.com.svg')

如下图：
