In-Depth Information
A user of this Web site can sort the states by acreage or by yield with respect to
a selected crop. Figure
.
, already discussed in more detail in Sect.
.
, shows LM
plots from this Web site for soybeans, with states sorted by decreasing yield. It is
possible to select another crop type and to access and download the raw data for
further analysis or additional maps such as the choropleth maps in Fig.
.
that are
based on these data. While a user who accesses this Web site gets the impression of
full interactivity, this is not the case. he ten micromaps (
crops
arrangements)
plus one overview micromap were precalculated in S-Plus (see Sect.
.
.
for more
details) and were stored as jpegimages. Itisnot possible tocreate any new micromap
display “on the fly” on this Web site. Precalculating all possible micromaps is oten
not possible or desirable for all datasets, as we will see in the next section.
Micromaps on the NCI Web Site
1.4.3
heNCIreleased the State CancerProfiles Websitein April
that providesinter-
active access to its cancer data via micromaps. his Website is Java based and creates
micromaps “on the fly.” Wang et al. (
) and Carr et al. (
) provide more de-
tails on the design of the NCI Web site, http://www.statecancerprofiles.cancer.gov/
micromaps.
LM plots with interactive and dynamic features are the main content on NCI's
State Cancer Profiles Web site that combines the latest research in data visualization
sponsoredbytheNSFDGQG initiative withfeatures toensureaccessibility bythevi-
suallyimpaired.heStateCancerProfilesWebsiteprovidesa“quickstop”forcancer-

theNCIincollaboration withtheCentersforDiseaseControl andPrevention (CDC)
and is an integral component of NCI's Cancer Control PLANET, a Web portal that
links to resources for comprehensive cancer control. he Web site provides national
(US), state, and county views of cancer statistics collected and analyzed in support
of annual federal reports. he focus is on eight major cancer types for which there is
evidence of the potential to improve outcomes either by prevention or by screening
and treatment.
Cancer statistics include mortality and incidence counts, rates, and trends by sex
and race/ethnicity. Recent incidence data are available for cancer registries partici-
pating in CDC's National Program of Cancer Registries (NPCR) that met selected
eligibility criteria. Both historical and recent incidence data are available for cancer
registries participating in NCI's Surveillance, Epidemiology and End Results (SEER)
program.Prevalenceofriskfactorsandscreening,HealthyPeople
USobjectives,
and demographics complete the profiles. he interactive graphic capabilities allow
auserof the Websiteto quickly explore patterns and potential disparities. For exam-
ple, the user can easily compare graphs of national (US) or state trends for Whites,
Blacks, Hispanics, Asian or Pacific Islanders, and American Indian/Alaskan Natives.
LM plots provide the primary graphic template for users to explore spatial relation-
shipsamongthe latest rates,percents,andcounts forcancer statistics, demographics,
risk factors, and screening.
