Chart — the most powerful data visualization plugin for Sketch

Create popular types of charts by real or random data.

The problem

Data visualization is an important part of work for many interface designers. Dashboards, tables, reports and widgets — all of these interface components contains charts. No matter which tool you use, Sketch, Figma or Adobe XD, you don’t have built-in features for data visualization.

Imagine that you want to create a prototype for an analysis tool or a system with dozens widgets, tables or reports using real data from Excel. I spent a few weeks doing the same task. And one day our data scientist came to me and said that all data had changed! I was forced to make changes to the 56 screens in my prototype…

What alternatives did I have? I could use Tableau, D3.js or HTML Canvas, but these tools are complicated and not much flexible. I decided that I had to find a Sketch plugin which could solve my problem.

After searching for an hour I find three interesting plugins: Sketch Data Studio, Sketch Pies and Sparkliner. Each of these plugins had pros and cons, and they didn’t satisfy all my needs. So I decided to create my own Sketch plugin for my daily visualization tasks.

About Chart

Chart contains four types of charts: Line chart, Bar chart, Area chart and Sparklines.

Each type of chart supports drawing on real text and tabulated or random data. You should copy numbers separated by commas from any text editor, Google sheet or Excel and create chart. If you select two or more strings, Chart will draw several lines on the canvas.
