This example shows the unemployment rate in 2014 for Spanish regions, ordered from highest to lowest, with bar lengths proportional to the rate and tooltips revealing the exact value per region. The chart uses d3.csv to load the data, d3.descending for sorting, and d3.select to append SVG rectangles with title elements for interactivity. The data is sourced from a CSV file containing regional unemployment statistics, and the visualization is rendered as a simple SVG bar chart.

Exercise Module 3

A horizontal bar chart displays the 2014 unemployment rate for each Spanish region, sorted from highest to lowest with grey bars sized proportionally to the rate. The visualization highlights that southern regions have higher unemployment while northern ones are lower, with hover tooltips revealing exact percentages. The code uses d3.csv to load region data and d3.selectAll with data joins to append SVG rect elements, scaling bar widths by multiplying the rate by eight.

Exercise Module 4

This graphic shows the 2014 unemployment rate for Spanish regions as a horizontal bar chart, with regions sorted from highest to lowest and the national average highlighted in a darker shade. It uses a linear scale for the value axis and an ordinal scale with range bands for the categorical region axis. The visualization is built with D3 v3, referencing the CSV data file for unemployment statistics, and uses SVG rendering with custom axes, hover tooltips, and a color scheme that emphasizes the national total.

Exercise Module 3

This visualization displays unemployment rates across Spanish regions in 2014, with a horizontally sorted bar chart ordering regions from highest to lowest rate. The chart uses D3 v3’s `d3.scale.linear` for the x-axis and `d3.scale.ordinal` with `rangeRoundBands` for the y-axis, rendering SVG rectangles. Hovering reveals tooltips via `append("title")`, while the total Spain value appears darker. Data comes from the Spanish Statistical Office (INE), and the axes use `d3.svg.axis`.

Exercise Module 5

A scatterplot shows the correlation between regional unemployment rates and the percentage of people reporting difficulty making ends meet across Spanish regions in 2014. Each circle represents a region, with the national average highlighted in darker gray. The visualization loads data from a CSV using `d3.csv`, sorts regions by unemployment rate, and animates circle radii from zero to five pixels via `transition.attr`. Axes are rendered with `d3.svg.axis`, and hover tooltips are added using SVG `title` elements. Data comes from the Spanish Statistical Office (INE).

Line Chart with Multiple Lines

This visualization examines unemployment across Spanish regions with two interactive SVG charts. The first chart displays 2014 unemployment rates as a horizontal bar chart, while the second tracks the evolution of these rates from 2007 to 2014 using a multi-line chart. The line chart uses d3.time.scale and d3.svg.axis to render annual data points, with hover effects that highlight individual paths. Regional CSV data is loaded and sorted via d3.csv, with the darkest bar representing the national total.

Bar Chart, Framed

This bar chart visualizes unemployment rates across Spanish regions in 2015, with bars colored in a dark red that deepens on hover to reveal the precise value. Built with D3 v3, the visualization is framed by a clean white background and uses an interactive hover effect—when the pointer passes over a bar, it fills with a rich crimson and the corresponding value label fades in, making it easy to compare regional unemployment data. The chart is part of a larger data exploration tool that includes additional views for scatterplots and line charts, all driven by user-controlled variable selection.

Line Chart with Multiple Lines

The visualization presents unemployment trends across Spanish regions from 2007 to 2014, with a supplementary bar chart detailing 2014 rates by region. It uses D3.js v3 to render SVG elements, including animated line paths that traverse the time series for each region, allowing hover highlighting to emphasize individual trends. The data is loaded from CSV files containing yearly unemployment percentages, with axes and scales built using d3.svg.axis and d3.time.scale.
