带有描述重复的值的条形图

Question

我有这样的数据：

('html5', 'javascript') ['ProductHunt', 'react-setup-with-php']
('javascript', 'react') ['money-money', 'react-setup-with-php']
('react', 'redux') ['money-money', 'react-redux-alpha']
('flask', 'pymysql') ['icd_mgn_demo', 'flask-indemetal-frota']
('python', 'calculator') ['Calculator_with_ExceptionHandling', 'calculator-tkinter-python']
('python', 'flask') ['microblog', 'flask-practice']
('flask', 'python') ['InstaFlask', 'flask-indemetal-frota']
('javascript', 'frontend') ['react-setup-with-php', 'react-tree']
('react', 'frontend') ['react-setup-with-php', 'react-tree']
('docker', 'dockerfile') ['dockerfile-images', 'wolfram-engine-docker']
('flutter', 'flutter-demo') ['Flutter-ConversorMoedas', 'flutter-BLoC-components']
('mod', 'dontstarve') ['OP-Cane', 'BetterClothes', 'Books-For-Everyone']
('flutter', 'flutter-examples') ['rebuilder', 'Flutter-ConversorMoedas', 'flutter-BLoC-components']
('vuejs', 'vuex') ['laravel-vue-spa-tailwindcss', 'ecommerce-vue', 'vuex-store-starter-cli']
('python', 'python3') ['Crypto-Converter', 'Formula-Project', 'cloudendure-python', 'madmac', 'python-myarray', 'InstaFlask', 'pysandbox']

其中数组表示它们的值，当然也表示它们的长度。 我想绘制以下条形图：

('html5', 'javascript') 2
('javascript', 'react') 2
('react', 'redux') 2
('flask', 'pymysql') 2
...

但与相应的值，在每个单位（箱）上的酒吧

比如：
