Sample Report 1
The line graph provides a detailed comparison of the population trends of three distinct animal species—bears, dolphins, and whales—in North America and its aquatic environments from 2011 to 2016, complemented by a pie chart that breaks down federal conservation funding allocations for these species over the same timeframe.
The overarching trend highlights significant growth in the bear population, a steady decline in dolphin numbers, and fluctuating figures for the whale populations. These trends are notably mirrored by the proportional distribution of government spending on conservation efforts, indicating a correlation between financial support and population sustainability.
In 2011, the bear population began as the smallest group, estimated at around 10,000 individuals. However, this number experienced a dramatic escalation over the following years, soaring to approximately 180,000 by 2016, showcasing the most substantial growth among the species studied. This rise corresponds closely with the allocation of nearly two-thirds of federal conservation funding to bear preservation, suggesting effective utilization of these resources.
Conversely, the dolphin population, which started at a robust figure of 150,000 in 2011, witnessed a stark and continuous decline over the five-year period, culminating in their complete disappearance by the end of 2016. This severe drop was paralleled by a minimal investment in dolphin conservation, receiving only 5% of total federal funds dedicated to species protection. Meanwhile, the whale population showed variable numbers, oscillating between 50,000 and 100,000, and ended the period on a downward trend, despite receiving a moderate focus in conservation efforts.

Sample Report 2
The provided line graph delineates the population trends of bears, dolphins, and whales in North America and its adjacent marine regions over a span from 2011 to 2016, alongside a pie chart that details federal spending on the conservation of these species within the same period.
Notably, the data reveal distinct trajectories in the populations of the three species, which are closely reflected in the allocation of conservation funding. The bear population exhibits robust growth, the number of dolphins steadily declines, and whale numbers fluctuate throughout the period examined.
Focusing on the specifics, the bear population commenced in 2011 with a modest count of approximately 10,000, which then escalated dramatically to reach about 180,000 by the year 2016. This sharp increase is concurrent with the substantial share of conservation funds directed towards bears, accounting for nearly two-thirds of the total expenditure. This substantial investment appears to correlate with the significant growth in their population over the six years.
Conversely, the dolphin population started at a much higher baseline of 150,000 in 2011 but experienced a precipitous decline over the period, eventually dwindling to zero by 2016. This decline mirrors the minimal financial support for dolphin conservation, which was a mere 5% of the federal budget dedicated to these species. Meanwhile, the whale population, receiving moderate financial attention, displayed variability in its numbers, ranging between 50,000 and 100,000, and concluded the period with a slight downward trend.

Sample Report 3
The line graph depicts changes in the populations of three animal species, including bears, dolphins, and whales, throughout North America and its marine habitats during a period of six years, from 2011 to 2016, while the pie chart illustrates the pace at which the federal government spends money on various species.
Overall, only the bear population had continuously high expansion, whereas dolphin numbers continued to decline the whole time. Both of these shifting patterns were clearly aligned to the federal government's level of funding for the preservation of the relevant species. Additionally, the whale population continued to fluctuate sporadically despite a moderate amount of state protection measures.
Initially throughout the period, bears were the least populous species in North America and its coastal areas, with just approximately 10,000 living there in 2011. However, in the following years, its population went through a steep increase and ended up with the highest number, which was roughly 180,000 in 2016. The situation with dolphins, on the other hand, was virtually the exact reverse of bears; in 2011, there were 150,000 dolphins, but their number sharply declined over the next two years, and it continued to decline until the end of the study period in 2016, when it completely disappeared.
However, whale population kept fluctuating between 50,000 and 100,000 throughout the years and ended the period with a diminishing trend. Meanwhile, when it comes to federal initiatives for protecting these species, nearly two thirds of the total spending went for bears that paid off with their continuous sharp rise in numbers. In contrast, just 5% of all government expenditure on species conservation was allocated for dolphin protection, leading to a sharp decline in the dolphin population over the course of the whole time.
