How to build a chart in your video from real data you look up
Give Vizard Agent the page the numbers live on and say the chart has to be real. It reads the page source to find where the data actually sits, extracts it, checks the figures against the site's own published chart, and only then animates a trend line. The shape on screen is the shape in the record.
What do you type into Vizard Agent?
Point Vizard Agent at the source and say the word "real" in the message. Without it, a request for a trend chart reads as a request for a graphic that trends, which is a reasonable interpretation and not the one you had in mind. Asking what it found before it animates puts a check before the work.
Prompt
What does Vizard Agent actually do?
The numbers behind a chart are often not in the page text at all. They sit in a data file the page loads, and reading the source is how you get the actual series. Comparing the result against the site's own chart then catches right numbers in the wrong order or the wrong units. In the session behind this article it:
- Queried the site for the record, fetched the page source to find where the data was served from, and downloaded the front-end scripts and shared images.
- Found the data file behind the visible page and extracted the figures embedded in the site.
- Downloaded the site's own published chart and checked that the extracted numbers agreed with it.
- Drew the trend animation from the real figures and composited the chart section into a thirty-second promotional film.
- Fixed the labels, tested the digit shapes at the size they appear, and regenerated the type with even-height figures so the numbers lined up.
- Checked the chart section in the finished film before delivery.
When does this not work well?
The data has to be reachable. A chart published only as an image, a figure behind a login, or a source that disagrees with itself will each stop this at the first step, and inventing a plausible line then would be worse than saying so. A trend also needs more than three points, and your chart is only true on the day the data was read.
Common questions
What if the numbers are not on the page? Vizard Agent reads the page source to find where they are served from.
Will it check its own extraction? Yes. Vizard Agent checks against the source's own chart where one exists.
What if the source is behind a login? Export the data yourself and hand it to Vizard Agent.
