數據來源
詳見“scrapy框架實現2019-nCoV省級疫情每日數據爬取”，僅爬取了2020-03-05的數據，以此爲例。
實現步驟
第一步：新建項目及應用配置
新建項目（需cd到指定位置）：
django-admin startproject yiqing_vs
新建應用（需cd到新建項目的目錄下）：
pyhton manage.py startapp vs
啓動服務，並訪問127.0.0.1:8000進行測試：
python manage.py runserver
測試成功，即可用pycharm打開項目進行路由等相關配置：
（1）yiqing_vs/settings.py（新增應用vs的配置）
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'vs.apps.VsConfig'
]
（2）yiqing_vs/urls.py（新增應用vs的路由配置信息）
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('vs/', include('vs.urls')),
path('', include('vs.urls'))
]
（3）vs/views.py（添加def）
from django.http import HttpResponse
def get_index_page(request):
return HttpResponse("hello world!")
（4）vs/urls.py（新建urls.py，並進行如下設置）
from django.urls import path, include
import vs.views
urlpatterns = [
path('vs', vs.views.get_index_page),
path('', vs.views.get_index_page),
path('/', vs.views.get_index_page),
]
（5）測試，如果http://127.0.0.1:8000成功返回“hello world！”，則表示配置成功。
第二步：頁面佈局
以Bootstrap柵格系統即可快速完成頁面佈局，並實現Carousel滾動播放。
引入Bootstrap及jQuery：
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css"
integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
<script src="http://cdn.bootcss.com/jquery/1.11.1/jquery.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.min.js"
integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa"
crossorigin="anonymous"></script>
Carousel部分代碼如下：
<div id="cj" class="col-md-12 cj"><!-- 上部控件-->
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
<li data-target="#carousel-example-generic" data-slide-to="1"></li>
<li data-target="#carousel-example-generic" data-slide-to="2"></li>
</ol>
<!-- Wrapper for slides -->
<div class="carousel-inner" role="listbox">
<div class="item active carl-img" style="background: url('../../../static/img/tx.png') no-repeat; background-size: 100% 100%;">
<p><a href="https://news.qq.com/zt2020/page/feiyan.htm#/" target="_blank"><img src="../../../static/img/tx.png" alt="騰訊疫情實時監測" ></a></p>
<div class="carousel-caption"></div>
</div>
<div class="item carl-img" style="background: url('../../../static/img/xl.png') no-repeat; background-size: 100% 100%;">
<p><a href="https://news.sina.cn/zt_d/yiqing0121" target="_blank"><img src="../../../static/img/xl.png" alt="新浪疫情實時監測" ></a></p>
<div class="carousel-caption"></div>
</div>
<div class="item carl-img" style="background: url('../../../static/img/bd.png') no-repeat; background-size: 100% 100%;">
<p><a href="https://voice.baidu.com/act/newpneumonia/newpneumonia" target="_blank"><img src="../../../static/img/bd.png" alt="百度疫情實時監測" ></a></p>
<div class="carousel-caption"></div>
</div>
</div>
<!-- Controls -->
<a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>
</div>
第三步：數據讀取及預處理
vs/views.py的def中實現，並在vs/urls.py中配置路由（之前已經做好了）。爲了測試，先在vs目錄下新建templates/vs/index.html
vs/views.py的def代碼如下：
def read_data(request):
dir = '../data/2020-3-5.csv'
data = pd.read_csv(dir)
# col_name: province_confirm province_dead province_heal province_name province_suspect
return data
def get_index_page(request):
data = read_data(request)
return render(request, 'vs/index.html')
測試成功則可以按需配置接口，這裏最重要的是注意數據格式，一般以數值或list傳參。
代碼如下（這裏的代碼有些冗餘，沒有優化處理，暫時只以能方便實現爲目標）：
def get_index_page(request):
# dir = '../data/2020-3-5.csv'
# data = pd.read_csv(dir, header=0)
data = read_data(request)
return render(request, 'vs/index.html',
{
"data": data.values.T.tolist()[1:],
"crawl_date": data["crawl_date"][0],
"province_name": data["province_name"][1:].to_list(),
"province_confirm": data["province_confirm"][1:].to_list(),
# "province_name": json.dumps(data["province_name"].to_list()),
# "province_confirm": json.dumps(data["province_confirm"].to_list()),
"province_dead": data["province_dead"][1:].to_list(),
"province_heal": data["province_heal"][1:].to_list(),
"province_suspect": data["province_suspect"][1:].to_list(),
"hubei_name": data["province_name"][0],
"hubei_confirm": data["province_confirm"][0],
"hubei_dead": data["province_dead"][0],
"hubei_heal": data["province_heal"][0],
"hubei_suspect": data["province_suspect"][0],
"hubei_data": [data["province_confirm"][0], data["province_dead"][0], data["province_heal"][0], data["province_suspect"][0]],
"name_all": data["province_name"].to_list(),
"confirm_all": data["province_confirm"].to_list(),
# "list_confirm": [data["province_name"], data["province_confirm"]],
"list_confirm": [list(data["province_name"]), list(data["province_confirm"])],
"list_confirm2": [list(data["province_name"][1:]), list(data["province_confirm"][1:])], # 除去湖北的省份
"sum_confirm": sum(data["province_confirm"][1:]), # 除去湖北的省份
"sum_dead": sum(data["province_dead"][1:]), # 除去湖北的省份
"sum_heal": sum(data["province_heal"][1:]), # 除去湖北的省份
"sum_suspect": sum(data["province_suspect"][1:]) # 除去湖北的省份
})
第四步：數據可視化圖表
導入相關js文件步驟：
（1）根目錄新建文件夾：static/js（如果需要，一併建立img和css文件夾）；
（2）配置yiqing_vs/settings.py：
# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/2.0/howto/static-files/
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
STATICFILES_DIRS = (
# ('css', os.path.join(STATIC_ROOT, 'css').replace('\\', '/')),
('js', os.path.join(STATIC_ROOT, 'js').replace('\\', '/')),
('img', os.path.join(STATIC_ROOT, 'img').replace('\\', '/')),
)
（3）相關文件放置其中，如果需要繪製中國地圖，則還需要導入china.js等文件；
（4）html文件引入相關js文件：
<script src="../../../static/js/echarts.js"></script>
<script src="../../../static/js/china.js"></script>
<script src="../../../static/js/bmap.js"></script>
<script src="../../../static/js/china-contour.js"></script>
每個圖表繪製均需讀入數據、初始化、設置、使用設置四個步驟：
<script type="text/javascript">
var list_confirm2 = {{ list_confirm2|safe }};
// 基於準備好的dom，初始化echarts實例
var myChart = echarts.init(document.getElementById("bar1"), theme);
// 指定圖表的配置項和數據
var option = {
title: {
...
},
tooltip: {
...
},
legend: [{
...
},{
...
}],
series: [{
...
}]
};
// 使用剛指定的配置項和數據顯示圖表。
myChart.setOption(option);
</script>
第五步：樣式調整及主題設置
樣式調整主要以css實現，這裏主要敘述echarts的主題設置：
（1）下載主題js文件：https://www.echartsjs.com/zh/download-theme.html
（2）主題.js放置於static/js目錄下；
（3）html引用.js：
<script src="../../../static/js/theme/dark.js"></script>
<script src="../../../static/js/theme/infographic.js"></script>
<script src="../../../static/js/theme/macarons.js"></script>
<script src="../../../static/js/theme/roma.js"></script>
<script src="../../../static/js/theme/shine.js"></script>
<script src="../../../static/js/theme/vintage.js"></script>
（4） 繪圖中使用主題（主題名稱與.js文件名對應）：
var theme = 'dark'
var myChart = echarts.init(document.getElementById("bar1"), theme);
（5）如果需要多個主題，我使用的是最笨的方法，即每個html對應一個主題，配置路由實現不同主題的訪問。
完整代碼
主要是index.html和views/urls.py的代碼。

特別說明
此數據可視化界面主要是爲了實踐echarts，部分圖表數據並非疫情真實獲取的數據，有部分數據是虛構數據，僅以實現圖表樣式爲目標。
注意事項
1、圖片實現居中佈局，親測最方便的方法——添加<p>：
.carl-img p{
text-align: center;
}
<div class="item active carl-img" style="background: url('../../../static/img/tx.png') no-repeat; background-size: 100% 100%;">
<p><a href="https://news.qq.com/zt2020/page/feiyan.htm#/" target="_blank"><img src="../../../static/img/tx.png" alt="騰訊疫情實時監測" ></a></p>
<div class="carousel-caption"></div>
</div>
2、文字居中佈局——設置行高：
.banner{
height: 120px;
font-size: 40px;
text-align: center;
line-height: 120px;
font-weight: bold;
}
存在的問題
可視化頁面的整體效果出來了，頁面細節的css還需完善。
