Which facilities credit out of proportion to their business? AC570's Unit 7 visualization critique shows a 31-slice pie hiding the answer and a sorted dot plot exposing it. Searches like "ac 570 unit 7 assignment example", "ac570 unit 7 sample" and "ac570 unit 7 example" land here.
What a finished AC570 Unit 7 visualization critique looks like
A copy of the original chart, a critique in five numbered points, the redesign and a note on what the redesign still cannot show, roughly four pages. The original is titled Credits by Facility, FY2025: a three-dimensional pie with 31 colored slices and a legend in facility-number order. Slices range from 2.06 to 4.85 percent of credit dollars, so Facility 9 at 4.85 and Facility 22 at 4.77 look barely larger than Facility 31 at 4.28. The redesign is a dot plot of credits as a percentage of billed rent, sorted from highest, with a line at the 6.25 percent median and another at twice it. Facility 9 sits at 19.51 and Facility 22 at 14.03, alone beyond the second line, with every other dot in gray.
How a AC570 Unit 7 example is structured
The critique begins by writing the question the chart should answer, because a chart can only be judged against a purpose. Five points then test the original against it. First, measure: dollars of credit reward size, so a large facility looks important whatever its behavior; Facility 19, the biggest at 713 units, holds 4.00 percent of dollars at a 5.99 percent rate, just under the median. Second, encoding: angles and areas across 31 slices cannot be ranked by eye. Third, the tilt enlarges front slices. Fourth, color spends 31 hues on identity and leaves none for emphasis. Fifth, no norm appears anywhere. The redesign answers each point in turn, and the closing note says what a ratio of credits to billed rent still leaves unexplained, such as a site filling empty units quickly.
The question the page should answer
Which facilities issue credits out of proportion to the rent they bill. Written first, since every later criticism depends on it.
A measure that rewards size
Share of credit dollars tracks facility size more than behavior. The largest site looks prominent while crediting slightly less than the median rate.
Angles nobody can rank
Thirty-one slices between 2.06 and 4.85 percent, tilted and exploded. Front slices gain apparent area, and the legend's order matches nothing in the pie.
One sorted row per facility
Credits over billed rent, highest first, a line at the 6.25 percent median and another at 12.50. Two dots stand past the second line while gray carries the rest.
What the ratio still hides
A site in lease-up bills little rent while granting many first-month credits, so a high ratio may reflect growth. The note flags this for the next discussion.
Where marks go in AC570 Unit 7
Criticism anchored in taste, too many colors or a dated look, scores poorly in AC570 because the unit judges a chart by how readily it delivers the comparison its reader needs, and a critique that never states that comparison has nothing to measure against. Graders credit the measure problem most heavily: raw dollars answer a question about size, not proportion. Redesigns that keep the dollar measure in a prettier form repeat the original flaw. Truncated or unlabeled axes in the redesign cost presentation points, as do titles naming a topic rather than a finding. Omitting a reference line leaves the reader unable to judge distance from normal. A closing note claiming the redesign settles which facility is misbehaving overstates what one ratio can show and invites a judgment comment.

AC570 Unit 7 questions, answered
Does the critique need a redesign?
Most AC570 prompts ask for one. Where it is optional, a redesign still demonstrates that the criticism was understood. A critique listing five faults with no alternative leaves the grader unsure the writer could fix them. The sample's redesign answers each numbered point in order, so the link between fault and fix is visible. Check your prompt; a few sections want two alternative designs compared.
Why a ratio instead of credit dollars?
Because the question concerns proportion. Dollars grow with facility size, so the biggest site dominates any dollar chart regardless of how it behaves. Dividing credits by billed rent puts every facility on the same footing. The sample also notes the ratio's weakness, that low-occupancy sites bill little rent, so the redesign is framed as a way to choose where to look rather than as a verdict.
Is a pie chart ever acceptable?
For two or three parts of a whole, where the reader needs a rough sense of share, it can work. With 31 parts of similar size it fails, since the eye cannot rank angles that close together, and a three-dimensional tilt makes it worse. Graders rarely penalize the chart type itself; they penalize a type that cannot carry the comparison the page is meant to make.
