Any CSV imported into this demo must meet the following assumptions in order to be processed successfully as time series data:

• The first row must consist of unique column headers.
• The first column must contain the datetimes for the time series. The datetime format may be ISO 8601 (preferred), or a "MM/DD/YYYY" style format with optional times (e.g. as exported from Excel) interpreted using the local time zone. If datetime parsing fails for a particular cell, the corresponding row will be dropped.
• All other columns are treated as numeric columns. Any non-numeric cells will be parsed as "NaN" values.
• The dataset must contain no more than 27 columns (including the date column) since the crossfilter library has a hard limit on the total number of dimensions.
