Imagine creating a timeline of your country’s whole history stretching back to its inception.
It would be no small task, and simply weighing the relative importance of so many great people, technological achievements, and pivotal events would be a tiny miracle in itself.
While that seems like a challenge, imagine going a few steps further. Instead of a timeline for just one country, what about creating a graphical timeline showing the history of the entire world over a 4,000 year time period, all while having no access to computers or the internet?
An All-Encompassing Timeline?
Today’s infographic, created all the way back in 1931 by a man named John B. Sparks, maps the ebb and flow of global power going all the way back to 2,000 B.C. on one coherent timeline.

Histomap, published by Rand McNally in 1931, is an ambitious attempt at fitting a mountain of historical information onto a five-foot-long poster. The poster cost $1 at the time, which would equal approximately $18 when accounting for inflation.
Although the distribution of power is not quantitatively defined on the x-axis, it does provide a rare example of looking at historic civilizations in relative terms. While the Roman Empire takes up a lot of real estate during its Golden Age, for example, we still get a decent look at what was happening in other parts of the world during that period.
The visualization is also effective at showing the ascent and decline of various competing states, nations, and empires. Did Sparks see world history as a zero-sum exercise; a collection of nations battling one another for control over scarce territory and resources?
Timeline Caveats
Crowning a world leader at certain points in history is relatively easy, but divvying up influence or power to everyone across 4,000 years requires some creativity, and likely some guesswork, as well. Some would argue that the lack of hard data makes it impossible to draw these types of conclusions (though there have been other more quantitative approaches.)
Another obvious criticism is that the measures of influence are skewed in favor of Western powers. China’s “seam”, for example, is suspiciously thin throughout the length of the timeline. Certainly, the creator’s biases and blind spots become more apparent in the information-abundant 21st century.
Lastly, Histomap refers to various cultural and racial groups using terms that may seem rather dated to today’s viewers.
The Legacy of Histomap
John Spark’s creation is an admirable attempt at making history more approachable and entertaining. Today, we have seemingly limitless access to information, but in the 1930s an all encompassing timeline of history would have been incredibly useful and groundbreaking. Indeed, the map’s publisher characterized the piece as a useful tool for examining the correlation between different empires during points in history.
Critiques aside, work like this paved the way for the production of modern data visualizations and charts that help people better understand the world around them today.
Without a map who would attempt to study geography? –John B. Sparks

Mapped: The Best Employer in Every U.S. State
Microsoft and Google dominate America’s best employers, but the company that ranks first varies widely from state to state.
America’s Top-Rated Employers, State by State
Key Takeaways
- Microsoft is the top-rated employer in nine states, the most of any organization, while Google leads in seven.
- Tech companies rank first in 19 states, more than any other sector.
- The winners range from NASA and Toyota to healthcare providers, banks, and major consumer brands.
This map shows the top-rated employer in every U.S. state in 2026, offering a snapshot of which large organizations earn the strongest marks from workers across the country.
The ranking is based on a Forbes survey of more than 245,000 employees. It covers organizations with at least 500 employees and considers pay, benefits, career growth, management, flexibility, and employee recommendations.
Big Tech Has the Widest Reach
Microsoft ranks first in nine states and Google in seven, meaning the two tech giants collectively lead nearly one-third of the country. Overall, tech companies take the top spot in 19 states.
Outside of tech, the results span a wide range of employers.
NASA leads in Alabama, Lockheed Martin in Louisiana, Toyota in Kentucky, and Trader Joe’s in California. Healthcare, finance, government, industrial, and consumer organizations also claim top spots across the country.
What Makes a Great Employer?
Pay is only one part of how Americans evaluate their workplaces. Benefits, career development, management, flexibility, and job security can also shape overall satisfaction.
In 2026, overall U.S. job satisfaction reached 68.9%, the highest level in 39 years and the 16th consecutive annual increase. That marks a sharp recovery from 2010, when satisfaction fell to 42.6% amid a weak post-recession labor market.
Income remains a major dividing line. Satisfaction ranged from 45.3% among workers in households earning under $25,000 to 76% among those earning $150,000 or more.
At the same time, the labor market remains uncertain, which may make job security more important to workers. Nearly four in 10 workers also said advanced AI improved their job satisfaction, adding another dimension to the changing workplace landscape.

Ranked: America’s 25 Best Cities for Work in 2026
Discover the best cities for work in 2026, ranked by job opportunities, compensation, career mobility, work-life balance, and more.
Ranked: America’s 25 Best Cities for Work in 2026
Key Takeaways
- Boston ranks as America’s best city for work in 2026, followed by Washington, D.C., and Burlington, Vermont.
- Burlington ranks first for job opportunity, while San Jose leads the country for compensation.
- Smaller metros including Madison, Fargo, and Sioux Falls rank among the strongest cities for job opportunities.
Where are the best places in America to build a career in 2026?
This visualization maps the 25 best cities for work from a ranking of 228 U.S. metro areas. The data comes from Indeed’s Best Cities for Work 2026.
Indeed evaluated metro areas with at least 200,000 residents across six pillars: job opportunity, compensation, job quality and security, career mobility, work-life balance, and economic opportunity.
Job opportunity and compensation each account for 20% of the overall score, while the other four categories each account for 15%.
Why Boston Ranks First for Work
Boston’s top ranking is driven by strength across several measures rather than dominance in a single category.
By category, Boston ranks second for career mobility and fifth for economic opportunity.
“For job seekers, the Boston-Cambridge ecosystem offers unusually strong access to healthcare, biotechnology and life sciences, higher education, and technology and professional services,” Indeed said in its ranking.
Washington, D.C., follows a similar pattern, ranking first for career mobility and third for compensation.
Smaller Cities Stand Out for Job Opportunities
Burlington leads all 228 metros for job opportunity, followed by Madison, Sioux Falls, Fargo, and Manchester.
Their strong showing highlights a different side of the ranking: several smaller metros offer particularly favorable conditions for finding work. Burlington and Madison also perform strongly across the broader set of measures, ranking third and sixth overall, respectively.
Tech Hubs Lead on Compensation
Some familiar technology centers dominate the compensation rankings.
San Jose ranks first for compensation, followed by Seattle, Washington, D.C., San Francisco, and Austin. But the leaders change substantially when other measures are considered.
Boulder ranks first for work-life balance, Charlottesville leads for job quality and security, and Rochester, Minnesota, tops economic opportunity. No metro leads all six categories, illustrating why the overall ranking looks different from a simple list of America’s highest-paying cities.
Ann Arbor, a college town and tech hub in southeast Michigan, is a notable all-around performer, ranking second for job quality and security, third for career mobility, and fifth for work-life balance.
