An AI chart is only as good as the numbers and the question you give it. Paste clean data, say what the chart should show, choose the shape that answers that question, and check every value in the result.
Capabilities reviewed 2026-09-26
Write one sentence about what the reader should learn: which region grew fastest, how spend split across teams, whether latency crossed the target. The question decides the chart type and what to emphasize.
Copy the cells from your spreadsheet and paste them into the prompt; they arrive as tab-separated rows, which work well. Vizify accepts image, audio, and video uploads only, so CSV, XLSX, and PDF files cannot be attached.
State what each number measures and in what unit (USD thousands, percent, milliseconds), the period it covers, and where it came from if the chart needs a source line. Mixed units in one series are the fastest way to a misleading chart.
Bars compare categories, lines show change over time, a pie or donut shows parts of one whole, a scatter shows the relationship between two measures, and a waterfall shows how a total was built up. If you are unsure, name the question and ask Vizify to recommend a shape.
Point to the one value or comparison that matters: the target line, the record quarter, the outlier. Also give sort order and any categories to group, so the chart does not bury the point.
Compare the rendered labels, values, axis ranges, and totals with your source data before sharing. If something is off, ask for a revision of the same chart rather than starting over.
Make a horizontal bar chart of Q3 revenue by region, sorted from highest to lowest. Units are USD thousands. Highlight EMEA as the fastest-growing region.
Region Q3 revenue
North America 1840
EMEA 1320
APAC 960
Latin America 410Why it works: The data is pasted as rows with a header, the unit is stated once, and the sort order and highlight are explicit.
Line chart of weekly p95 API latency in milliseconds for the last 8 weeks. Add a horizontal reference line at the 300 ms target and label the weeks that exceed it.
Week p95 ms
W1 240
W2 255
W3 310
W4 290
W5 335
W6 280
W7 265
W8 250Why it works: Time runs along the x-axis in order, the threshold is a stated value, and the annotation rule is spelled out instead of left to the model.
Donut chart of this month's marketing spend by channel. Values are in USD and should total 50,000. Show percentages on the chart and put the total in the center.
Paid search: 18,000
Social: 12,500
Events: 9,000
Content: 6,500
Other: 4,000Why it works: Giving the expected total lets you and Vizify catch a mistyped value, and a donut only makes sense when the parts sum to one whole.
Scatter chart of ad spend (x-axis, USD) against sign-ups (y-axis) for these 10 campaigns. Label each point with the campaign name. Do not add a trend line.
[paste campaign, spend, sign-ups rows here]Why it works: Both axes are named with units, point labels are requested, and the prompt rules out an added trend line you did not ask for.
I want to show how our annual budget moved from last year's 2.4M to this year's 2.9M through five changes: +0.6M headcount, +0.2M tooling, -0.15M travel, -0.1M office, -0.05M other. Recommend the clearest chart type and then create it.Why it works: When the question is clear but the shape is not, asking for a recommendation lets Vizify pick a format such as a waterfall before it generates.
The same table can produce very different charts. Quarterly revenue by region can be a bar chart comparing regions, a line chart showing each region’s trend, or a stacked bar showing how the total is composed. None of them is wrong, but only one answers the question you have. Writing that question into the prompt, such as “which region grew fastest this quarter”, lets Vizify choose the layout and the emphasis instead of guessing.
Vizify has two chart engines and chooses between them by chart type. Mermaid handles the types it supports natively, including XY charts for bars and lines, pie charts, quadrant charts, radar charts, Sankey diagrams, and treemaps. Vizify Chart covers the formats Mermaid does not have, including area, scatter, donut, heatmap, histogram, funnel, waterfall, box plots, and business frameworks such as SWOT or a risk matrix. You can name either engine if you have a preference; otherwise Vizify picks the one that supports the chart you asked for, and tells you when neither does rather than substituting a different chart.
Either way, Vizify keeps your values, units, order, and labels as supplied, and it will not fill gaps with invented figures. If you want placeholder data for a mockup, ask for it and it will be labeled as example data.
Chart generation is a gated action. Accounts without Pro or a credit pack get two chart generations in total, and both creating and revising a chart count, whichever engine produces it. Get the data and the question right in the first prompt, and batch several corrections into one revision request rather than sending them one at a time.
Not as a file. Vizify uploads accept images, audio, and video only. Copy the cells you need from the spreadsheet and paste them into the prompt; they arrive as tab-separated rows.
Paste only what the chart needs. A bar chart stays readable with about a dozen categories and a line chart with a few series. Summarize or aggregate large tables before pasting.
Vizify uses Mermaid for chart types it supports natively, such as bar and line charts, pie charts, and quadrant charts, and Vizify Chart for formats Mermaid does not have, such as scatter, donut, heatmap, funnel, and waterfall charts.
No. Vizify preserves the values, units, and labels you supply and only generates demonstration data when you explicitly ask for it, in which case it is labeled as example data.
Yes. Ask for a change to the same chart, such as a new sort order, a different highlight, or corrected values. Each revision counts toward the chart allowance on accounts without Pro or a credit pack.
Describe the question you want answered and ask Vizify to recommend a chart type before creating it. The chart tools on the Site are also organized by shape if you want to start from one.
No. Vizify does not browse the web or read PDF files. Collect the figures yourself and paste them with their source.
Two chart generations in total, shared between Mermaid and Vizify Chart and between creating and revising. After that, charts need Vizify Pro or a credit pack.
