    ## Data Assistant (experimental)

    Ask questions about the landvote data, like:

    - What are the top states for approved conservation funds?
    - Plot the total funds spent in conservation each year.
    - What city has approved the most funds in a single measure? What was the description of that vote?
    - Which state has had largest number measures fail? What is that as a fraction of it's total measures?
