29:null 2a:["$","title",null,{"children":"Introduction to D3: Course Assignment | Bob-Richard-DIS | Observable"}] 2f:T440,### Certificate The D3 course **assignment is due by October 20th**! Once you have completed your assignment, use the **[form linked here](https://forms.gle/8ri7VVziyBn6Feyd8)** to submit. Once we have received your submission, we'll review it and give you feedback. Also, since we've gotten some questions about pro vs. free user accounts: you do not need a pro account to complete and submit the assignment. We do need you to make the notebook visible to us, though, so check your [Sharing permissions](https://observablehq.com/@observablehq/sharing?collection=@observablehq/editing-publishing-collaborating) before submission. If you're a free user, the default sharing is public, so shouldn't have to do anything. ### Videos and course materials If you missed any of the lectures, you can watch (or re-watch) all the lesson recordings here. All of the course materials can be found in this collection.30:T2da9, // // // Minnesota Barley Crop Experiment // // // //
