  # div class="p" rather than <p>: the notes below are a ul, which is block level and not legal

    <div class="p">
      This chart shows only work items that have started but not completed, grouped by the column
      they're currently in. Hovering over a dot will show you the ID of that work item.
    </div>
    <div class="p">
      The shaded areas indicate what percentage of the work has passed that column within that time.
      Notes:
      <ul>
        <li>It only shows columns that are considered "in progress". If you see a column that wouldn't normally
        be thought of that way, then likely issues were moving backwards or continued to progress after hitting
        that column.</li>
        <li>If you see a colour group that drops as it moves to the right, that generally indicates that
          a different number of data points is being included in each column. Probably because tickets moved
           backwards athough it could also indicate that a ticket jumped over columns as it moved to the right.

The last visible column is excluded from the right-boundary history search because ages_of_issues_when_leaving_column inflates its age_data (it uses today as the end date when there's no next column), so it's kept only when it has a current aging item.
