Write an AI chart summary grounded in the actual data

The direct answer

Give an AI assistant the exact columns, year, source and allowed claims before asking for a chart explanation. For the internet-use and life-expectancy sample, request an observed comparison and explicit limitations rather than a causal story.

Prepare the observation table

Join the 2023 internet_pct and life_expectancy_years columns by iso3. Make a scatter plot and verify two points manually. If optional Datamon AI is configured, ask it to describe this table only. The same prompt can be used as a manual review checklist without an AI service.

Public dataset and a reproducible example

The download is a prepared extract, not a live data connection. The source links below include the original query, observation period and reuse policy. Keep an original copy when you update the data; revised source values can change the result.

World Bank WDI values retain the indicator units and country-year definitions. Derived counts and indexes are Datamon tutorial calculations, not new official World Bank statistics.

Build it in Datamon

Sign in with Google to create an editable visualization. Public articles and examples can be read without an account. The prepared CSV already contains the joins, filters or aggregations described above; do those steps in a spreadsheet first when using your own data.

Open Data and choose a file, or paste the table with its header row. Check the detected numeric columns, decimal separator and dates. The current importer accepts files below 20 MB; these examples are smaller. Keep blanks distinct from recorded zeros.
In Visualize, select Scatter plot. Connect the roles exactly as listed below. Review the preview against at least two rows in the example table rather than relying only on automatic mapping.
In Refine, add a title that states the question, the unit, observation period and source. Check labels and contrast at the size your reader will see. Keep a table when exact values matter.
Use the export controls for SVG, PNG, PDF or PowerPoint, then inspect the actual file. Save an editable project backup. Publish only after checking the underlying values: a public link makes the published data available to anyone possessing the URL.

Calculation and column mapping

The rule below is pseudocode. The downloadable CSV already contains the prepared values; spreadsheet functions and cell references depend on your sheet layout.

JOIN internet and life expectancy ON iso3 AND year = 2023

X: internet_pct
Y: life_expectancy_years
Point label: country

Read the result

In this extract, life_expectancy_years ranges from 69.83 (PHL) to 84.04 (JPN).

Use the preview to check the structure and the CSV to check exact values. Its styling is a reference; your Datamon rendering can look different. Follow the mapping and preparation above to reproduce the analytical meaning.

Mistakes that change the meaning

An AI response is a draft interpretation. Check every number against the table and reject invented sources, forecasts, or claims that internet use causes longer life. Optional AI requests transmit relevant context to the configured service; use the public sample for practice.

A prompt tied to the table

Use only the attached 2023 table and its cited World Bank indicators. Describe the observed relationship between internet_pct and life_expectancy_years for these ten countries. Quote two country values with units. State that the sample is selected, and that association does not establish causality. Do not invent sources, missing values, forecasts or market-demand claims.

Questions before sharing

Do these calculations require an AI service?

No. The prepared CSV and reference calculation are deterministic. Optional AI can help draft an explanation when configured, but it does not replace checking source values or choosing a valid comparison.

Can I use this example with my own spreadsheet?

Yes. Keep the same observation unit, column types and calculation. Replace the source attribution and time period, recompute derived columns, then compare several output values with your original sheet before sharing.

What is free and what needs an account?

Reading this guide and downloading its CSV and chart images are free. Datamon currently has no paid checkout or subscription plans in this deployment. Creating and saving an editable visualization requires Google sign-in. Provider-backed AI, cloud analysis, publishing and video depend on configured services; this guide does not promise unlimited free connected services.
