Chart Type Selection
4 promptsType from Question
1/16✨ What it does
ChatGPT picks a chart type for [question + data] with a recommendation, alternatives, and when each works: bar, line, scatter, pie (at most 4 slices), or a table. Fill question and data, then draw the recommended type on your first pass.
For [question + data], best chart type. Output: recommendation + alternatives + when each. Common: bar (compare), line (trend), scatter (correlation), pie (parts, ≤4 slices), table (specifics). Match visual to question.
Pro tip: Wrong chart type = obscures data. Bar > pie for compare (almost always). Pie acceptable only for ≤4 slices showing parts of 100%. Match question, not data.
Bar vs Column
2/16✨ What it does
ChatGPT explains bar (horizontal, long names, ranked lists) versus column (vertical, time series, fewer categories) so you pick the right orientation. Choose bar if labels are long, then swap if the chart is a short time series.
Bar chart vs column chart. Output: bar (horizontal, good for long category names, ranked lists) vs column (vertical, good for time series, fewer categories). Different uses.
Pro tip: Bar (horizontal): long labels readable, good for ranked top-N lists. Column (vertical): time series, fewer items. Default to column unless labels long; then bar.
Line vs Area
3/16✨ What it does
ChatGPT explains line versus area: line for trends, multiple series, and precise values; area for cumulative totals, parts of a whole over time, or a single series. Pick line if you have several series, then avoid stacking them into a muddy area.
Line chart vs area chart. Output: line for: trend, multiple series, precise values. Area for: cumulative totals, parts of whole over time, single series. Different cognitive loads.
Pro tip: Line = precise trend. Area = mass + flow. Multiple lines OK; multiple stacked areas = often confusing. Default to line; area for cumulative narratives.
Scatter vs Bubble
4/16✨ What it does
ChatGPT explains scatter versus bubble: scatter for two-variable correlation, bubble when a third dimension (size) matters. Use scatter if two variables are enough, then add bubbles only if size is a real measure in your data.
Scatter vs bubble plot. Output: scatter for 2-variable correlation. Bubble adds 3rd dimension via size. When 3-variable matters, bubble; when 2 enough, scatter.
Pro tip: 2-variable correlation = scatter. Adding size dimension (e.g., revenue + growth + market size) = bubble. 3rd dimension via size; humans struggle with 4+.

Design Principles
4 promptsChart Junk Removal
5/16✨ What it does
ChatGPT strips chart junk from [Describe chart]: drop 3D, minimize gridlines, keep legends only when needed, use fewer labels, and make color purposeful. Describe the chart, then delete the 3D and extra grid before you present it.
[Describe chart]. Remove chart junk: 3D effects (avoid), gridlines (minimal), legends (only when needed), labels (minimum useful), colors (purposeful only). Less = more.
Pro tip: Default chart software adds: gridlines, dark borders, legends, 3D effects, fancy colors. Strip back to data + minimal context = professional. Tufte's data-ink principle.
Title-as-Takeaway
6/16✨ What it does
ChatGPT rewrites a chart title as the takeaway, so Q3 revenue grew 30% instead of a topic label like Q3 Revenue. Write the takeaway title, then check that the chart actually supports your sentence.
Chart title-as-takeaway. Output: not "Q3 Revenue" (topic) but "Q3 revenue grew 30%" (takeaway). Title carries the message.
Pro tip: Topic titles = "what is this chart about?" Takeaway titles = "here's the point." Titles should pass standalone test: read just titles, get the story.
Axis Honesty
7/16✨ What it does
ChatGPT sets honest axes: y usually starts at 0 (truncation misleads), with exceptions for a tight range, unit labels, and clearly marked axis breaks. Start at zero unless the range is tight, then label the units before you screenshot it.
Honest axes. Output: y-axis usually starts at 0 (truncating misleads), exception (data range tight), label units, axis breaks if needed (clearly marked). Truncation = manipulation accusation.
Pro tip: Truncated y-axis can mislead (small change looks huge). Default: start at 0. Exception: data range very tight (e.g., 99.5%-99.7% uptime). Then break clearly marked.
Color Choice
8/16✨ What it does
ChatGPT chooses chart color: one highlight plus gray instead of a rainbow, color as meaning not decoration, and categorical versus sequential versus diverging scales. Highlight one series, then gray the rest so your point is obvious.
Color in charts. Output: 1 highlight color + neutrals (gray) > rainbow palette. Color encodes meaning; not decoration. Categorical (distinct colors) vs sequential (gradient) vs diverging (red-blue).
Pro tip: Rainbow chart = "everything important" = nothing important. Highlight + gray = "this matters." Color encoding intentional. Most charts over-color.
Common Mistakes
4 promptsPie Chart Misuse
9/16✨ What it does
ChatGPT flags pie-chart misuse: more than 5 slices, comparing two pies, 3D distortion, and similar slices you cannot tell apart, and usually recommends bars instead. Switch to a bar if you have more than five slices, then drop the 3D pie.
Pie chart misuse. Output: >5 slices unreadable, comparing 2 pies hard (use stacked bar), 3D pies distort, similar-sized slices indistinguishable. Most pie charts should be bars.
Pro tip: Pie charts work only for: ≤4 slices, parts of 100%, single comparison. Almost always: bar chart better. Default to bar; reach for pie only when explicitly justified.
Dual-Axis Charts
10/16✨ What it does
ChatGPT explains dual-axis charts: when two related metrics on different scales are justified, how they mislead, and alternatives such as small multiples or indexed values. Avoid a second axis unless your metrics are related, then consider small multiples first.
Dual-axis charts (two y-axes). Output: when justified (related metrics in different scales), when misleading (manipulation easy), alternatives (small multiples, indexed values).
Pro tip: Dual-axis charts can mislead by manipulating either axis. Reader can't tell what's "high" or "low." Often better: small multiples (separate charts) or normalize to indexed values.
Time-Series Issues
11/16✨ What it does
ChatGPT fixes time-series issues: mark irregular intervals, show gaps instead of interpolating missing data, keep date formats consistent, and manage x-axis density. Mark the gaps on your next chart, then stop connecting missing points.
Time-series chart issues. Output: irregular intervals (mark them), missing data (show gaps, not interpolation), date format consistency, x-axis density. Time-series special.
Pro tip: Time-series with missing data interpolated = misleading. Show gaps explicitly. Irregular intervals (different spacing) = stretches reality. Treat time honestly.
Comparison Trap
12/16✨ What it does
ChatGPT catches a comparison trap where two periods share a chart but not the same scale, units, or window. Rebuild the comparison on one scale, then drop the chart if your periods are not comparable.
Comparison trap: 2 different time periods on same chart with different scales. Output: comparison must be apples-to-apples (same units, same scale, same time periods). Otherwise misleading.
Pro tip: Comparing absolute numbers across periods of different lengths = wrong. Normalize: per-day, per-customer, indexed to base. Apples-to-apples mandatory.

Specialty Charts
4 promptsSmall Multiples
13/16✨ What it does
ChatGPT designs small multiples (a grid of small charts) for many series or breakdowns, with consistent scales, a logical sort, and why that beats one crowded chart. Keep every small chart on the same scale, then sort them so your story is easy to scan.
Small multiples (grid of small charts). Output: when useful (comparing many series, breakdowns), how to design (consistent scales, sorted logically), advantages over single chart with many series.
Pro tip: Small multiples = many small charts side-by-side. Beats single chart with 20 lines (spaghetti). Each small chart focuses; brain compares grid. Underused; powerful.
Heatmap Design
14/16✨ What it does
ChatGPT designs a heatmap for [data] covering when a value matrix or calendar of frequency works, a sequential color scale, labeling, and an alternative if the heatmap is noisy. Fill the data, then add labels or switch to a table if your colors blur.
Heatmap for [data]. Output: when useful (matrix of values, calendar of frequency), color scale (sequential), labeling, alternative if heatmap noisy. 2D categorical visualization.
Pro tip: Heatmap = matrix shaded by value. Useful for: weekly patterns by hour, correlation matrices. Color scale matters: sequential for magnitude, diverging for above/below mean.
Sankey Diagram
15/16✨ What it does
ChatGPT designs a Sankey for [flow data] covering conversion funnels and energy-style flows, design notes, and tools such as D3, online builders, or built-in BI. Name the flow, then keep the node count low enough for you to read.
Sankey diagram for [flow data]. Output: when useful (flow visualization, conversion funnel, energy flow), design considerations, tools (D3, online tools, BI built-in). Specialized.
Pro tip: Sankey = flow visualization. User journey through funnel, energy flow, budget allocation. Powerful when flow matters. Don't use for non-flow data.
Bullet Chart
16/16✨ What it does
ChatGPT designs a bullet chart for a KPI versus target, with a bar, target marker, range bands, use cases, and why it beats a gauge. Build the bullet for your main KPI, then retire the gauge if it is only decorative.
Bullet chart (KPI vs target). Output: design (single bar with target marker + range bands), use cases, why better than gauge for KPIs.
Pro tip: Bullet chart > gauge chart for KPIs. Gauges hard to read precisely. Bullet shows: actual, target, performance bands. Few BI tools have built-in; worth learning.
