I also wanted to know trends. Is it getting better? i.e. Is the number of new cases per day dropping and the total cases curve flattening out.
This is a sample of the most critical areas (e.g. New York City) and areas where I have friends and family.

At the advice of my, Son, a medical journal editor, I've changed this to report deaths which is likely more accurate than cases.
Case numbers are under reported because of a lack of testing, pre-symptomatic, and non-symptomatic people, which vary by location.
There are issues with death counts too, but fewer than with case counts.
See Deaths vs Cases.

Second tier - Other developed countries with 100 or more total deaths per 1 million population

On June 6 Brazil stoped reporting confirmed cases, saying the numbers were not accurate.

On May 12, the Washington Post reported that Labanon, Iran, and Wuhan had reimposed lockdowns following and increase in infections. South Korea also tightened some restrictions that were removed.

* Deaths per Case or the Case Fatality Rate (CFR) is all over the place for a variety of reasons. See Case Fatality Rate
Italy, Spain, France and the UK all had over 10% deaths per case, probably because it hit so fast there they didn't have facilities to treat all the sick.

1.East Asia, Japan, South Korea, Taiwan, Hong Kong and Singapore, experience with SARS has helped to keep well ahead of the infectious curve through a combination of early response, pervasive screening, contact tracing, comprehensive testing, and the adroit use of technology. Universal healthcare, clear management structures for the public health response.
Wired says, "These countries all have social structures and traditions that might make this kind of surveillance and control a little easier than in the don’t-tread-on-me United States"

2. Wuhan is in Hubei Province. Hubei Province accounts for 80% of the cases in China. China is not counting asymptomatic cases and some people think there are other discrepancies in their counting.

Hubei Province China, which includes Wuhan, has a population of 60 million and 67,803 thousand infected (0.1% of the population) (84% of China's total) .
Isolated by distance and a lack of transportation western China does not seem to be infected.
Hunan Province adjoining Hubei only had 1,018 infections.
Some people have questioned China's reporting.

More data below

Coronavirus patients in South Korea, Wuhan and some in Japan are now testing positive for the virus a second time with no symptoms. It's not clear whether these are false positives or dormant virus which may or may not be activated.

Note: The number of infectious people is higher because pre-symptomatic and asymptomatic (18%-40%) people,
A recent study found that nearly half of patients in Singapore and 62% of patients in Tianjin, China transmitted the virus when they were pre-symptomatic.

Note: US testing is behind other countries so it may be higher.
Leveling off may not last. With only 1 out of 1,000 having natural immunity from being infected there could be 2nd and 3rd waves. Epidemiologists are saying we may need 50-60% immunity from contracting the disease and/or a vaccine to achieve "herd immunity" and stop it from spreading without extraordinary efforts.

I've looked at places where I have friends and family or places which were considered hot spots in the news. I'd be 12 times more likely to run into someone with coronavirus in the county I came from in New Jersey than in Yolo County, California where I live now.

March 19 Stay at home order (Shelter in Place) All individuals living in the State of California are currently ordered to stay home or at their place of residence, except for permitted work, local shopping or other permitted errands.
Essencial Services:

• Gas stations
• Pharmacies
• Food: Grocery stores, farmers markets, food banks, convenience stores, take-out and delivery restaurants
• Banks
• Laundromats/laundry services
• Childcare

May 8 the stay home order was modified. In addition to essential activity, retail is allowed, along with the infrastructure to support it. California restaurants and shopping malls can soon reopen in counties that meet state standards for testing and success at reducing cases of the coronavirus,

May 26, 2020, Hair salons and barber shops will be allowed to reopen in 47 of the state's counties after being closed because of the coronavirus pandemic.

On June 12 most California Counties were allowed to move to Stage 3 with some indoor dining with table spacing, hotels, outdoor recreation and other facilities allowed to open.

Most Bay Area counties were still restricted.

Seven of the nine Bay Area counties have reported recent, significant upticks in cases, and the Bay Area as a whole recorded a nearly 40% jump in new cases
Source: Coronavirus cases on the rise across the Bay Area, especially in Alameda County - SFChronicle.com, May 26.

On June 18 as new cases in California continued to increase, the Governor announced masks were mandetory in high-risk settings where 6' separation could not be achieved.

On July 1 Governor Newsom announced 19 counties must close indoor restaurants, wineries, tasting rooms, movie theaters, family entertainment centers, zoos, museums and cardrooms for at least three weeks. If possible, those businesses can operate outdoors. Bars and breweries, indoors and outdoors, have been ordered to close..
Contra Costa, Fresno, Glenn, Imperial, Kern, Kings, L.A., Merced, Orange, Riverside, Sacramento, San Bernardino, San Joaquin, Santa Barbara, Santa Clara, Solano, Stanislaus, Tulare., and Ventura.

>July 8 The state is monitoring data for elevated disease transmission (case rates and positive test results), increased hospitalizations and limited hospital capacity (availability of ICU beds and ventilators). Any county not meeting threshold criteria in at least one category goes on the watch list.
Marin was on the list and decided to halt indoor dining for at least three weeks in response. Santa Clara was no longer on the list but the previous restrictions remain based on having been on the list for three or more consecutive days.

See new case trend by county at SF Chronicle

Note: Studies at the beginning of May by the The COVID Tracking Project and others show an infection rate an order of magnitude higher that that reported by the CDC.

The variation of deaths per case is influenced by a number of factors such as inaccurate case counts and vulnerability, age distribution, overall health -- e.g. percent of the population with high blood pressure, etc.
See real case numbers below and Case Fatality Rate (CFR)..

I included population density thinking there would be a correlation with infection rate. It was weak, Santa Clara, San Francisco and Marin were outliers with much higher infection rates than population density would predict. I needed to include other factors like average age to zero in on density.
There was a correlation nationwide.

Santa Clara County California, the heart of Silicon Valley, had the highest rate in the state at the end of March.

Epidemic - A quick rise in the number of cases of a disease beyond what is normally expected in a geographical area.
Pandemic - A disease that has spread across many countries and affects a large number of people.
Endemic - An infection which is constantly maintained at a baseline level in a geographic area without external inputs. For example, chickenpox is endemic (steady state) in the UK, but malaria is not.
