title: How to render data to chart in email
body: <p>This days I have a demand that shows some data in email. The data have been stored in MySQL, then I have to render this data to line chart or other chart and 
  embed it in email every day(the data in every day is different).I want to make this process automatically. How do I achieve it? Some solution may be need.</p>
  
  <p>I have searched from google and find a way: <strong>D3.js</strong> and <strong>Phantomjs</strong> and <strong>Node.js</strong>, D3.js renders the chart, Phantomjs makes the chart to image, Node.js serves as the server to render data in MySQL to D3 chart and serves as the image server.</p>
  
  <p>But I can not determine this way can be achieved.How about the way? </p>
