Charted is a tool for automatically visualizing data, created by the Product Science team at Medium. Provide the link to a data file and Charted returns a beautiful, interactive, and shareable chart of the data. Charted is deliberately sparse in formatting and data transformation options, and instead gives you a few powerful core features:

• Rendering well on all screen sizes, including monitors
• Re-fetching the data and updating the chart every 30 minutes
• Moving data series into separate charts
• Adjusting the chart type, labels/titles, and background

Charted treats the first column of the data file as the labels for the x-axis and all subsequent columns as y-series values. Charted does not parse the first column (x-axis), but instead always equally spaces the data points along the x-axis.

Charted currently supports csv files (including links to csv files on Dropbox) and Google Spreadsheets. The settings for Dropbox links and Google Spreadsheets must both be set to publicly shareable.

To try Charted out, simply download the repo and run npm install to install dependencies. After that you will be able to run npm start. This will start a server at localhost:3000.
