The chart displays student grades as vertical bars, with student codes on the x-axis and grade values on the y-axis. Each bar’s height encodes the grade, and hovering over a bar triggers a tooltip showing the exact grade value. The visualization uses d3.v3 with SVG rendering, leveraging `d3.scale.ordinal` and `d3.scale.linear` for axes, and the d3-tip library for interactive tooltips. Data comes from an inline array of student codes and grades, with axes rotated for readability.

AI-generated description

<b>What: </b> <br> Table<br> one categorical attribute : code <br> one quiantitative attribute: grade

<b>Why:</b> <br> Present-Distribution <br> lookup-values <br>

<b>How:</b> <br> Separate horizontally (code) <br> Aligned vertically (grade) <br>

<b>Argumentation </b> <br>

<p> For the students the essential is to know their grades, because of this, in the diagram are shown the grades with the student code and not only the grades. Considering this, the bar diagram is chosen for the representation. Line is chosen as the market, because it helps to represent with the help of the length of it a grade. In the horizontal axis are the codes and in the vertical axis are the grades, starting with 0 and finishing a little more than five. They are chosen in this oreder because it is easier to compare, vertically, the grades between students. </p>

A bar chart displays exam grades for a list of student codes, with each bar’s height representing the grade and the horizontal axis showing the code. Hovering over a bar reveals the exact grade via a tooltip. Built with D3 v3, it uses ordinal and linear scales, SVG axes, and the d3-tip library for interactive tooltips.

Tarea 3: Visualización calificaciones

A bar chart displays student grades, identified by student code along the x-axis and grade value on the y-axis, with a red line marking the class average. The bars are colored orange and turn darker on hover. Using d3.v3 and the d3-tip library, hovering over a bar reveals the exact grade via a tooltip. The chart is rendered as an SVG, with d3.scale.ordinal and d3.scale.linear handling the axes, and d3.mean calculates the average line shown. Data is embedded directly in the script as a JSON array.

Tarea3

This visualization displays student grades as individual data points plotted along a single quantitative axis. The scatterplot uses a linear x-scale with an oriented bottom axis, though the y-axis remains unused. The code loads grade data from an embedded array of objects and renders dots with stroke outlines. It relies on D3 v4 for the main visualization, while also loading D3 v3 for the axis and scale APIs, mixing both versions. The SVG rendering includes margin-based positioning and a placeholder text element, but no interactive features or additional encodings are implemented.

gradesBlock

A bar chart displays the grades of a set of students, with each bar representing a student’s code on the x-axis and their grade on the y-axis. The visualization uses D3 v3 with SVG rendering, and hover interactions trigger a tooltip via the d3-tip plugin to show the exact grade and code. A button labeled "Organizar" sorts the data by grade and repaints the chart. The chart uses orange bars that darken on hover, with axes labeled "Estudiantes" and "grades".

gradesBlock

This bar chart displays student grades, where each orange bar represents an individual student’s code and grade. Users can hover over any bar to view a tooltip with the exact grade and code, or click the "Organizar" button to sort the data by grade. The visualization uses D3 v3 with SVG rendering, applying ordinal and linear scales for axes, and the d3-tip library for interactive tooltips.

D3: Linked charts

A bar chart displays student grades from a dataset of student IDs and numeric grade values, with each bar representing a student. The visualization uses linked charts to show grades and allows sorting by ascending or descending order. Built with D3.js, it uses SVG rendering with animated bar transitions and axes. The bars are color-coded using hue and saturation, and hovering highlights individual bars to reveal exact grade labels. The data appears to be sample grade records with student IDs, and the chart is designed to compare grade distributions across students.

Homework #3

This visualization presents student grades as a set of circles positioned along a common scale from 0 to 6 on the x-axis, with student codes on the y-axis. Each circle is colored based on its distance from the class average: green for the maximum grade, red for the minimum, blue for grades within one standard deviation, orange for those within two standard deviations, and purple for outliers beyond that. The visualization uses position and color hue to support tasks of presenting grades and discovering extreme values, and includes animated text labels for grades, interactive tooltips on mouseover, and gridlines to aid in comparison across the distribution.

Students Grades of Bar Chart

This horizontal bar chart displays student grades, with each student’s name on the y-axis and their corresponding numerical grade on the x-axis. The visualization uses D3 v5’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to render the SVG bars. Data is loaded from a CSV file, and interactive features include tooltips on mouseover and an alert on click, triggered via `select` and event listeners. Grid lines and axis labels are conditionally configured through a chart configuration object.
