When plotted, reveals starkly \ndifferent patterns: one shows a linear relationship, another a non-linear curve, the third a near-perfect linear \nrelationship disrupted by a single outlier, and the fourth a near-vertical line of points where a single outlier \nentirely dictates the regression.\n\nIn his 1973 paper \"Graphs in Statistical Analysis\" Yale Professor [Francis Anscombe](https://archives.yale.edu/repositories/12/resources/3711) uses these four datasets \nto argue that visualization is essential to good statistical work, not merely an optional supplement. This was a radical position at a \ntime when most statistical analysis was done through batch processing on mainframes with no graphical output. Serves \nas a powerful demonstration that identical summary statistics can mask radically different patterns in data, making the case that \nstatistical analysis should combine both numerical calculations and graphical examination.  \n",

Based on graphic designer \nWill Burtin's 1951 visualization of antibiotic effectiveness, originally published in Scope Magazine and\nfeatured as an example in the Protovis project, a precursor to D3.js.\n\nNumerical values represent the minimum inhibitory concentration (MIC) of each antibiotic, \nmeasured in units per milliliter, with lower values indicating higher antibiotic\neffectiveness.\n\nAs noted in the Protovis example, \"Recreating this display revealed some minor errors in the original: a missing grid line at 0.01 μg/ml, and an exaggeration of some values for penicillin\".\n\nThe vega-datsets version is largely consistent with the Protovis version, with one correction (changing 'Brucella antracis' to the correct 'Bacillus anthracis') and the addition of a new column, 'Genus', to group related bacterial species together.\n\nThe caption of the original 1951 [visualization](https://graphicdesignarchives.org/wp-content/uploads/wmgda_8616c.jpg) \nreads as follows:\n\n> #### Antibacterial ranges of Neomycin, Penicillin and Streptomycin\n>\n>\n> The chart compares the in vitro sensitivities to neomycin of some of the common pathogens (gram+ in red and gram- in blue) with their sensitivities to penicillin, and streptomycin.\n>\n> The effectiveness of the antibiotics is expressed as the highest dilution in μ/ml. which inhibits the test organism.\n>\n> High dilutions are toward the periphery; consequently the length of the colored bar is proportional to the effectiveness.\n>\n> It is apparent that neomycin is especially effective against Staph. albus and aureus, Streph. fecalis, A. aerogenes, S. typhosa, E. coli, Ps. aeruginosa, Br. abortus, K. pneumoniae, Pr. vulgaris, S. schottmuelleri and M. tuberculosis.\n>\n> Unfortunately, some strains of proteus, pseudomonas and hemolytic streptococcus are resistant to neomycin, although the majority of these are sensitive to neomycin.\n>\n> It also inhibits actinomycetes, but is inactive against viruses and fungi. Its mode of action is not understood.\n",

Nightingale credits Dr. William Farr for \ncompiling the data from the 1858 [Medical and Surgical History of the British Army](http://resource.nlm.nih.gov/62510370R). Categorizes \ndeaths into \"zymotic\" diseases (preventable infectious diseases), wounds/injuries, and other causes. \nCovering the period from April 1854 to March 1856, it includes monthly army strength \nalongside mortality figures. Transformed by Nightingale into her now-famous [polar area \ndiagrams](https://iiif.lib.harvard.edu/manifests/view/drs:7420433$25i). \n\nThe annual mortality rates plotted in the chart can be calculated using the formula \n> (Deaths × 1000 × 12) ÷ Army Size. \n\nAs [The Lancet](https://pmc.ncbi.nlm.nih.gov/articles/PMC7252134/) argued in 2020, Nightingale's \ninnovative visualizations proved that \"far more men died of disease, infection, and exposure \nthan in battle—a fact that shocked the British nation.\" Her work also vividly illustrated \nthe dramatic impact of sanitary reforms, particularly in reducing preventable deaths.",

Gapminder's data documentation notes that its philosophy is to fill data \ngaps with estimates and use current geographic boundaries for historical data. Gapminder \nstates that it aims to \"show people the big picture\" rather than support detailed numeric \nanalysis.\n\nNotes:\n1. Country Selection: The set of countries matches the version of this dataset \n   originally added to this collection in 2015. The specific criteria for country selection \n   in that version are not known. Data for Aruba are no longer available in the new version. \n   Hong Kong has been revised to Hong Kong, China in the new version.\n\n2. Data Precision: The precision of float values may have changed from the original version. \n   These changes reflect the most recent source data used for each indicator.\n\n3. Regional Groupings: To preserve continuity with previous versions of this dataset, we have retained the column \n   name 'cluster' instead of renaming it to 'six_regions'. \n",

Obtained from IPUMS USA, which \"collects, preserves and harmonizes U.S. census microdata\" from as early as 1790.\n\nOriginally created for a 2006 data visualization project called *sense.us* by IBM Research (Jeff Heer, Martin Wattenberg and Fernanda Viégas), described [here](https://homes.cs.washington.edu/~jheer/files/bdata_ch12.pdf). \nThe dataset is also referenced in this vega [example](https://vega.github.io/vega/examples/job-voyager/).\n\nBased on a tabulation of the [OCC1950](https://usa.ipums.org/usa-action/variables/OCC1950) variable by sex across IPUMS USA samples. Appears to be derived from Version 6.0 (2015) of IPUMS USA, according to 2024 correspondence with the IPUMS Project. IPUMS has made improvements to occupation coding since version 6, particularly for 19th-century samples, which may result in discrepancies between this dataset and current IPUMS data. Details on data revisions are available [here](https://usa.ipums.org/usa-action/revisions).\n\nIPUMS USA confirmed in 2024 correspondence that hosting this dataset on vega-datasets is permissible, stating:\n>We're excited to hear that this dataset made its way to this repository and is being used by students for data visualization. We allow for these types of redistributions of summary data so long as the underlying microdata records are not shared.\n\n1. Represents summary data. Underlying microdata records are not included.\n2. Users attempting to replicate or extend this data should use the [PERWT](https://usa.ipums.org/usa-action/variables/PERWT#description_section) \n(person weight) variable as an expansion factor when working with IPUMS USA extracts.\n3. Due to coding revisions, figures for earlier years (particularly 19th century) may not match current IPUMS USA data exactly.\n\nWhen using this dataset, please refer to IPUMS USA [terms of use](https://usa.ipums.org/usa/terms.shtml).\nThe organization requests use of the following citation for this json file:\n\nSteven Ruggles, Katie Genadek, Ronald Goeken, Josiah Grover, and Matthew Sobek.

While the dataset shows their reign as 1689-1702, \nthe official Web site of the British royal family indicates that Mary II's reign ended in 1694, though William III continued to rule until 1702.\nThe `commonwealth` field is used to flag the period from 1649 to 1660, which includes the Commonwealth of England, the Protectorate, \nand the period leading to the Restoration. While historically more accurate to call this the \"interregnum,\" the field name of `commonwealth` \nfrom the original dataset is retained for backwards compatibility.\n\n> [!IMPORTANT]\n> Revised in Aug. 2024 to show James II's reign now ends in 1688 (previously 1689).\n\nSource data has been verified against the kings & queens and interregnum pages of the official website of the British royal family (retrieved in Aug. 2024).\n",
