Designing informational treatment: displaying inputted answers vs. correct answers

You can easily use Google charts to show such visualization in qualtrics. Demo of the same.

Hi rondev. Thanks for the reply. I'm specifically interested in displaying to respondents their inputted answers vs. the correct answers. I'm not sure how this can be done from the Demo you shared. Is there any additional literature you can share with me? Thanks!

It could be as simple as an html table with piped values:

Hey Tom,
Thanks for the reply. I'm a novice with this kind of stuff. What exactly goes into '(pipe for Item 1 estimate)'? Or perhaps the question I mean to ask is how to locate the 'pipes' in which respondents' estimates are stored (?). For instance, consider a 'slider' item in which respondents are asked to estimate the share of the US population that is 'married'. How do I find/connect those values (as inputted by the sliding scale) to the table so that respondents are shown their initial estimates (leaving aside the correct figures for now)?

Update: I figured out how to load the piped values into a table. Now I just need to figure out how to load them (ideally) into a Google chart. Can you point me in the right direction? Thanks again for your help!

Pipe the values into the JS inside quotes. For example:
var x = "${q://QIDx/xyz}";
If the JS expects a number:
var x = Number("${q://QIDx/xyz}");
