COURSE · DATA VISUALIZATION
A visualization can contain accurate data and still be hard to understand. When chart choice, color, or presentation competes with the message, the audience has to work harder to discover what matters.
Técnicas de Visualización de Datos is a concise course designed to help you choose, review, and improve visualizations with clearer criteria. It combines fundamentals, applied examples, and concrete chart corrections so you can make data easier to follow when you present it.
The course itself is taught in Spanish.

Turning numbers into bars, lines, or colors is only the beginning. When you prepare a presentation, report, or spreadsheet, the important question is different: what does the person looking at these data need to notice first?
A good visual decision makes that reading easier because the chart matches the comparison, color directs attention, and elements that do not help stop competing with the main finding.
For example, a bar chart, a line chart, and a pie chart can all contain correct numbers while producing very different readings. The useful skill is choosing the form that most closely matches what you need to explain, because different comparisons call for different visual forms.
First define what the audience should understand. Then decide how to show it.
You will review bar charts, line charts, pie charts, and other formats to recognize which representation makes a comparison or change easier to read. The goal is not to memorize an endless list of rules, but to build criteria you can reuse.
The course includes concrete chart examples that can be improved. For example, seeing what changes before and after a correction can help you notice similar problems in your own reports and presentations.
Color can organize, emphasize, or distract. You will learn to treat it as a functional decision: if it is there, it should help the audience understand what matters.
Before choosing a chart, it helps to know what the audience should understand. The course connects visualization and narrative so the form supports the message instead of becoming decoration.
The course includes applied examples, a reference to Excel templates, and a chart-review checklist. To be clear, Excel appears as one practical resource; this is not an Excel course. The main focus is the judgment behind choosing and improving visualizations.
According to the current listing, the course includes 4 sections, 20 lessons, and approximately 45 minutes of content. It begins with visualization fundamentals, moves through basic charts and concrete corrections, then expands into other chart types and the use of color.
No prior knowledge is required.
The format may fit if you want a clear introduction that helps you review charts more deliberately. If you need a long program, intensive exercise-based training, or deep instruction in one specific tool, review the syllabus before enrolling to make sure the format matches what you are looking for.

Take a visualization you already have and ask:
If those questions reveal something you would change, you already have a glimpse of the kind of judgment the course develops.
It is designed for people who work or study with data and need to present them more clearly; for people who prepare reports, spreadsheets, or presentations; and for people who already build charts but want better criteria for reviewing visual decisions.
It can also fit if you need a short foundation before you move into more specialized tools or disciplines.
This format may not be right if you are looking for extensive training, a course centered entirely on one tool, or long exercise-based sessions. Before enrolling, review the syllabus and compare it with what you need.
What matters is not adding more to the chart. It is making the important information easier to see.
When you review a visualization, use that rule as a filter: remove what distracts, choose a form that matches the comparison, use color for a reason, and decide what the audience should notice first.
Message first. Chart second.
